Abstract
Identification of genetic sequence variations occurring on a population-wide scale is key to unraveling the complex interactions that are the underlying cause of many medical disorders and diseases. A critical need exists, however, for advanced technology to enable DNA mutation analysis to be performed with significantly higher throughput and at significantly lower cost than is currently attainable. Microfluidic systems offer an attractive platform to address these needs by combining the ability to perform rapid analysis with a simplified device format that can be inexpensively mass-produced. This paper will review recent progress toward developing these next-generation systems and discuss challenges associated with adapting these technologies for routine laboratory use.

Abstract
Genotyping of single nucleotide polymorphisms (SNPs) allows diagnosis of human genetic disorders associated with single base mutations. Conventional SNP genotyping methods are capable of providing either accurate or high-throughput detection, but are still labor-, time-, and resource-intensive. Microfluidics has been applied to SNP detection to provide fast, low-cost, and automated alternatives, although these applications are still limited by either accuracy or throughput issues. To address this challenge, we present a MEMS-based SNP genotyping approach that uses solid-phase-based reactions in a single microchamber on a temperature control chip. Polymerase chain reaction (PCR), allele specific single base extension (SBE), and desalting on microbeads are performed in the microchamber, which is coupled with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to analyze the SBE product. Experimental results from genotyping of the SNP on exon 1 of the HBB gene, which causes sickle cell anemia, demonstrate the potential of the device for rapid, accurate, multiplexed and high-throughput detection of SNPs.

Abstract
Fast and accurate detection of single-nucleotide polymorphism (SNP) is thought more and more important for understanding of human physiology and elucidating the molecular based diseases. A great deal of effort has been devoted to developing accurate, rapid, and cost-effective technologies for SNP analysis. However most of those methods developed to date incorporate complicated probe labeling and depend on advanced equipment. The DNAzyme based Gap-LCR detection method averts any chemical modification on probes and circumvents those problems by incorporating a short functional DNA sequence into one of LCR primers. Two kinds of exonuclease are utilized in our strategy to digest all the unreacted probes and release the DNAzymes embedded in the LCR product. The DNAzyme applied in our method is a versatile tool to report the result of SNP detection in colorimetric or fluorometric ways for different detection purposes.

Abstract
The results of investigations into performing DNA sequencing chemistry on a picoliter-scale electrowetting digital microfluidic platform are reported. Pyrosequencing utilizes pyrophosphate produced during nucleotide base addition to initiate a process ending with detection through a chemiluminescence reaction using firefly luciferase. The intensity of light produced during the reaction can be quantified to determine the number of bases added to the DNA strand. The logic-based control and discrete fluid droplets of a digital microfluidic device lend themselves well to the pyrosequencing process. Bead-bound DNA is magnetically held in a single location, and wash or reagent droplets added or split from it to circumvent product dilution. Here we discuss the dispensing, control, and magnetic manipulation of the paramagnetic beads used to hold target DNA. We also demonstrate and characterize the picoliter-scale reaction of luciferase with adenosine triphosphate to represent the detection steps of pyrosequencing and all necessary alterations for working on this scale.

Abstract
This review describes recently emerging optical and microfluidic technologies suitable for point-of-care genetic analysis systems. Such systems must rapidly detect hundreds of mutations from biological samples with low DNA concentration. We review optical technologies delivering multiplex sensitivity and compatible with lab-on-chip integration for both tagged and non-tagged optical detection, identifying significant source and detector technology emerging from telecommunications technology. We highlight the potential for improved hybridization efficiency through careful microfluidic design and outline some novel enhancement approaches using target molecule confinement. Optimization of fluidic parameters such as flow rate, channel height and time facilitates enhanced hybridization efficiency and consequently detection performance as compared with conventional assay formats (e.g. microwell plates). We highlight lab-on-chip implementations with integrated microfluidic control for "sample-to-answer" systems where molecular biology protocols to realize detection of target DNA sequences from whole blood are required. We also review relevant technology approaches to optofluidic integration, and highlight the issue of biomolecule compatibility. Key areas in the development of an integrated optofluidic system for DNA hybridization are optical/fluidic integration and the impact on biomolecules immobilized within the system. A wide range of technology platforms have been advanced for detection, quantification and other forms of characterization of a range of biomolecules (e.g. RNA, DNA, protein and whole cell). Owing to the very different requirements for sample preparation, manipulation and detection of the different types of biomolecules, this review is focused primarily on DNA-DNA interactions in the context of point-of-care analysis systems.

Identification of SNPs and INDELS in swine transcribed sequences using short oligonucleotide microarrays. BMC Genomics 2008; 9:252.

Abstract
Background Genome-wide detection of single feature polymorphisms (SFP) in swine using transcriptome profiling of day 25 placental RNA by contrasting probe intensities from either Meishan or an occidental composite breed with Affymetrix porcine microarrays is presented. A linear mixed model analysis was used to identify significant breed-by-probe interactions. Results Gene specific linear mixed models were fit to each of the log2 transformed probe intensities on these arrays, using fixed effects for breed, probe, breed-by-probe interaction, and a random effect for array. After surveying the day 25 placental transcriptome, 857 probes with a q-value ≤ 0.05 and |fold change| ≥ 2 for the breed-by-probe interaction were identified as candidates containing SFP. To address the quality of the bioinformatics approach, universal pyrosequencing assays were designed from Affymetrix exemplar sequences to independently assess polymorphisms within a subset of probes for validation. Additionally probes were randomly selected for sequencing to determine an unbiased confirmation rate. In most cases, the 25-mer probe sequence printed on the microarray diverged from Meishan, not occidental crosses. This analysis was used to define a set of highly reliable predicted SFPs according to their probability scores. Conclusion By applying a SFP detection method to two mammalian breeds for the first time, we detected transition and transversion single nucleotide polymorphisms, as well as insertions/deletions which can be used to rapidly develop markers for genetic mapping and association analysis in species where high density genotyping platforms are otherwise unavailable. SNPs and INDELS discovered by this approach have been publicly deposited in NCBI's SNP repository dbSNP. This method is an attractive bioinformatics tool for uncovering breed-by-probe interactions, for rapidly identifying expressed SNPs, for investigating potential functional correlations between gene expression and breed polymorphisms, and is robust enough to be used on any Affymetrix gene expression platform.

Abstract
A novel two-step process was developed to prepare ssDNA templates for pyrosequencing. First, PCR-amplified DNA templates modified with an acrylamide group and acrylamide monomers were copolymerized in 0.1 M NaOH solution to form polyacrylamide gel spots. Second, ssDNA templates for pyrosequencing were prepared by removing electrophoretically unbound complementary strands, unmodified PCR primers, inorganic pyrophosphate (PPi), and excess deoxyribonucleotides under alkali conditions. The results show that the 3-D polyacrylamide gel network has a high immobilization capacity and the modified PCR fragments are efficiently captured. After electrophoresis, gel spots copolymerized from 10 microL of the crude PCR products and the acrylamide monomers contain template molecules on the order of pmol, which generate enough light to be detected by a regular photomultiplier tube. The porous structure of gel spots facilitated the fast transportation of the enzyme, dNTPs and other reagents, and the solution-mimicking microenvironment guaranteed polymerase efficiency for pyrosequencing. Successful genotyping from the crude PCR products was demonstrated. This method can be applied in any laboratory; it is cheap, fast, simple, and has the potential to be incorporated into a DNA-chip format for high-throughput pyrosequencing analysis.

Abstract
To explore genome variation meaningfully, there is a critical need for a high-throughput and inexpensive platform for DNA analysis. Pyrosequencing is a nonelectrophoretic bioluminometric DNA sequencing method that uses a four-enzyme mixture reaction to monitor nucleotide incorporation in real time. Currently, the commercialized pyrosequencing technique is limited to a 96-microtiter plate format. However, high throughput and inexpensive pyrosequencing is required to meet the need of screening large numbers of samples. We present here DNA pyrosequencing on a nanoliter-volume microfluidic platform. The microfluidic approach involves the trapping of the DNA on microbeads in an on-chip filter chamber and flow-through of the pyrosequencing reagents to monitor the reaction in real time. Two single-nucleotide polymorphisms were successfully scored to evaluate the microfluidic platform. In addition to significantly reducing reagent costs, microfluidic systems promise to improve the read length by eliminating intermediate product accumulation by constant removal of unincorporated nucleotides and elimination of dilution effects at each reaction cycle in the current plate format. Although only one filter chamber was used in this study, the platform should be readily adaptable to parallel analyses of nanoliter samples using filter chamber arrays to obtain high-throughput DNA analysis.

Abstract
Abstract
Background: Hemoglobinopathies are the most common inherited diseases worldwide. Various methods for genotyping of hemoglobin, beta (HBB) gene mutations have been reported, but there is need for a high sample-throughput, cost-effective method for simultaneous screening of several mutations. We report a method that combines the high detectability and dynamic range of chemiluminescence with the high allele-discrimination ability of probe extension reactions for simultaneous genotyping of 15 HBB mutations in a high sample-throughput, dry-reagent format.
Methods: We genotyped the HBB mutations IVSI-110G>A, CD39C>T, IVSI-1G>A, IVSI-6T>C, IVSII-745C>G, IVSII-1G>A, FSC6GAG>G-G, −101C>T, FSC5CCT>C−, IVSI-5G>A, FSC8AAG>−G, −87C>G, IVSII-848C>A, term+6C>G, and HbS (cd6GAG>GTG). The method used comprises the following: (a) duplex PCR that produces fragments encompassing all 15 mutations, (b) probe extension reactions in the presence of fluorescein-modified dCTP, using unpurified amplicons, and (c) microtiter well-based assay of extension products with a peroxidase-antifluorescein conjugate and a chemiluminogenic substrate. We used lyophilized dry reagents to simplify the procedure and assigned the genotype by the signal ratio of the normal-to-mutant–specific probe.
Results: We standardized the method by analyzing 60 samples with known genotypes and then validated by blindly genotyping 115 samples with 45 genotypes. The results were fully concordant with sequencing. The reproducibility (including PCR, probe extension reaction, and chemiluminometric assay) was studied for 20 days, and the CVs were 11%–19%.
Conclusions: This method is accurate, reproducible, and cost-effective in terms of equipment and reagents. The application of the method is simple, rapid, and robust. The microtiter well format allows genotyping of a large number of samples in parallel for several mutations.

Abstract
In the past few years, electrophoresis microchips have been increasingly utilized to interrogate genetic variations in the human and other genomes. Microfluidic devices can be readily applied to speed up existing genotyping protocols, in particular the ones that require electric field-mediated separations in conjunction with restriction fragment analysis, DNA sequencing, hybridization-based techniques, allele-specific amplification, heteroduplex analysis, just to list the most important ones. As a result of recent developments, microfabricated electrophoresis devices offer several advantages over conventional slab-gel electrophoresis, such as small sample volume requirement, low reagent consumption, the option of system integration and easy multiplexing. The analysis speed of microchip electrophoresis is significantly higher than that of any other electric field-mediated separation techniques. State-of-the-art microfluidic bioanalytical devices already claim their place in most molecular biology laboratories. This review summarizes the recent developments in microchip electrophoresis methods of nucleic acids, particularly for rapid genotyping, that will most likely play a significant role in the future of clinical diagnostics.

Abstract
Pyrosequencing is a highly effective method for quantitatively genotyping short genetic sequences, but it currently is hampered by a labor-intensive sample preparation process designed to isolate single-stranded DNA from double-stranded products generated by conventional PCR. Here linear-after-the-exponential (LATE)-PCR is introduced as an efficient and potentially automatable method of directly amplifying single-stranded DNA for pyrosequencing, thereby eliminating the need for solid-phase sample preparation and reducing the risk of laboratory contamination. These improvements are illustrated for single-nucleotide polymorphism genotyping applications, including an integrated single-cell-through-sequencing assay to detect a mutation at the globin IVS 110 site that frequently is responsible for beta-thalassemia.
