Abstract
Over the past two decades significant technical advancement in the field of western blotting has been made possible through the utilization of microfluidic technologies. In this review we provide a critical overview of these advancements, highlighting the advantages and disadvantages of each approach. Particular attention is paid to the development of now commercially available systems, including those for single cell analysis. This review also discusses more recent developments, including algorithms for automation and/or improved quantitation, the utilization of different materials/chemistries, use of projection electrophoresis, and the development of triBlots. Finally, the review includes commentary on future advances in the field based on current developments, and the potential of these systems for use as point-of-care devices in healthcare.

Anal Biochem 2017; 523:39-43. [PMID: 28137604 DOI: 10.1016/j.ab.2017.01.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Revised: 01/22/2017] [Accepted: 01/25/2017] [Indexed: 10/20/2022]
Abstract
A ring-shaped electroeluter (RSE) was designed for protein recovery from polyacrylamide gel matrix. The RSE was designed in such a way that a ring-shaped well was used to place gel slices and an enrichment well was used to collect eluted protein samples. With HSA as model protein, the electroelution time was less than 30 min with 80% recovery rate, and the concentration of recovered protein was 50 times higher than that of conventional method. The RSE could be reused at least ten times. The developed device makes great advance towards economic electroelution of biomolecules (such as proteins) from gel matrix.

ADVANCED MATERIALS (DEERFIELD BEACH, FLA.) 2016; 28:327-334. [PMID: 26567472 PMCID: PMC4708057 DOI: 10.1002/adma.201503939] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2015] [Revised: 10/05/2015] [Indexed: 05/18/2023]
Abstract
Pore-gradient microgel arrays enable thousands of parallel high-resolution single-cell protein electrophoresis separations for targets accross a wide molecular mass (25-289 kDa), yet within 1 mm separation distances. Dual crosslinked hydrogels facilitate gel-pore expansion after electrophoresis for efficient and uniform immunoprobing. The photopatterned, light-activated, and acid-expandable hydrogel underpins single-cell protein analysis, here for oncoprotein-related signaling in human breast biopsy.

Abstract
Polyacrylamide electrophoresis is routinely used for small-scale preparative and analytical separations. The incomparably high-resolution separations achieved by this technique, however, have not been widely exploited to the large-scale preparative isolation of biological molecules from contaminants, mainly because of difficulties in the recovery of the desired molecule from the gel matrix. Electroelution is an effective procedure applied for this purpose. However, commercially available, high-cost electroeluters are required for achieving high recovery yields. Here, we describe a custom-made electroeluter that combines low-cost, high-recovery yields, short times of electroelution, and convenience in the manipulation of sensitive samples.

Abstract
Traditional real-time polymerase chain reaction (PCR) requires a purified DNA sample for PCR amplification and detection. This requires PCR tests be conducted in clean laboratories, and limits its applications for field tests. This work developed a method that can carry out DNA purification, amplification and detection in a single PCR tube. The polypropylene PCR tube was first treated with chromic acid and peptide nucleic acids (PNA) as DNA-capturer were immobilized on the internal surface of the tube. Cauliflower mosaic virus 35S (CaMV-35S) promoter in the crude extract was hybridized with the PNA on the tube surface, and the inhibitors, interfering agents and irrelevant DNA in the crude extract were effectively removed by rinsing with buffer solutions. The tube that has captured the target DNA can be used for the following real-time PCR (RT-PCR). By using this approach, the detection of less than 2500 copies of 35S plasmids in a complex sample could be completed within 3 hours. Chocolate samples were tested for real sample analysis, and 35S plasmids in genetically modified chocolate samples have been successfully identified with this method in situ. The novel One-PCR-tube method is competitive for commercial kits with the same time and simpler operation procedure. This method may be widely used for identifying food that contains modified DNA and specific pathogens in the field.
