Abstract
A highly sensitive reverse sandwich immunoassay for the detection of human cardiac myoglobin (cMb) in serum was designed utilizing a gold nanoparticle (AuNP)-enhanced surface plasmon resonance (SPR) biosensor. First, a monoclonal anti-cMb antibody (Mab1) was covalently immobilized on the sensor surface. AuNPs were covalently conjugated to the second monoclonal anti-cMb antibody (Mab2) to form an immuno-gold reagent (Mab2-AuNP). The reverse sandwich immunoassay consists of two steps: (1) mixing the serum sample with Mab2-AuNP and incubation for the formation of cMb/Mab2-AuNP complexes and (2) sample injection over the sensor surface and evaluation of the Mab1/cMb/Mab2-AuNP complex formation, with the subsequent calculation of the cMb concentration in the serum. The biosensor signal was amplified approximately 30-fold compared with the direct reaction of cMb with Mab1 on the sensor surface. The limit of detection of cMb in a human blood serum sample was found to be as low as 10 pM (approx. 0.18 ng mL(-1)), and the inter-assay coefficient of variation was less than 3%. Thus, the developed SPR-based reverse sandwich immunoassay has a sensitivity that is sufficient to measure cMb across a wide range of normal and pathological concentrations, allowing an adequate estimation of the disease severity and the monitoring of treatment.

Abstract
In this study, we report a simple, low-cost surface plasmon resonance (SPR)-sensing cartridge based on a loop-mediated isothermal amplification (LAMP) method for the on-site detection of the hepatitis B virus (HBV). For LAMP detection, a SPR based LAMP sensing system (SPRLAMP) was constructed, including a novel SPRLAMP sensing cartridge integrating a polymethyl methacrylate (PMMA) micro-reactor with a polycarbonate (PC)-based prism coated with a 50 nm Au film. First, we found that the change of refractive index of the bulk solution was approximately 0.0011 refractive index (RI) units after LAMP reaction. The PC-based prism's linearity and thermal responses were compared to those of a traditional glass prism to show that a PC-based prism can be used for SPR measurement. Finally, the HBV template mixed in the 10 μl LAMP solution could be detected by SPRLAMP system in 17 min even at the detection-limited concentration of 2 fg/ml. We also analyzed the correlation coefficients between the initial concentrations of HBV DNA templates and the system response (ΔRU) at varying amplification times to establish an optimal amplification time endpoint of 25 min (R(2)=0.98). In conclusion, the LAMP reaction could be detected with the SPRLAMP sensing cartridge based on direct sensing of the bulk refractive index.

Biosens Bioelectron 2011; 30:73-7.

Abstract
A novel one-step electrochemical method for DNA detection is described. The procedure utilizes a reaction catalyzed by a peroxidase-mimicking DNAzyme to produce a product, which forms an insoluble precipitation layer on the surface of an electrode. A rationally designed forward primer, conjugated with a peroxidase DNAzyme complementary sequence at its 5'-end, is used for PCR amplification of target DNA. As a result, the DNAzyme sequence is produced by amplification only when the target DNA is present in the sample. The PCR product is then subjected to the precipitation reaction on the electrode surface using an electrolyte assay buffer containing 4-chloronaphthol, hydrogen peroxide, ferrocenemethanol, hemin, and 5'-lambdaexonuclease. Finally, analysis is carried out using Faradaic impedance spectroscopy. The impedance value was found to greatly increase when target DNA is present owing to the formation of a precipitation layer on the electrode surface caused by the catalytic action of the DNAzyme. In contrast, no impedance increase is observed when a control sample not containing target DNA is utilized. By employing this strategy, target DNA from Chlamydia trachomatis was reliably detected within a 10 min period following precipitation without the need for complicated secondary procedures. This effort has led to the development of a highly convenient electrochemical one-step method for DNA detection that utilizes a peroxidase-mimicking DNAzyme, which is specifically designed to undergo amplification during PCR of target DNA.

Abstract
This article presents a simple chronoamperometric immunosensor for the quantitative assessment of creatine kinase MB (CK-MB) in 50 microL undiluted serum samples. The immunosensor consists of gold working and counter electrodes patterned onto a glass chip by thin-film photolithography and an external Ag|AgCl reference electrode. The detection limit (DL) of the chronoamperometric method is 13 ng mL(-1) (DL = 2xRMSD/S, where RMSD is the residual mean standard deviation of the measured points around a calibration curve with a slope of S). In spiked serum samples, the response was linear up to 300 ng mL(-1) of CK-MB. A surface plasmon resonance (SPR) system with simultaneous electrochemical detection (EC-SPR) aided the development of the sandwich immunoassay. Real-time monitoring of the SPR signal was used to optimize the capture antibody immobilization, CK-MB and detection antibody binding, as well as to minimize the nonspecific adsorption of serum proteins to the sensor surface. The detection antibody has been labeled with alkaline phosphatase (ALP) enzyme for sensitive electrochemical detection. ALP catalyzes the hydrolysis of ascorbic acid phosphate and generates ascorbic acid, which is measured chronoamperometrically. The electrochemical immunoassay for CK-MB was less sensitive to nonspecific adsorption related interferences, had a better detection limit, and required a lower volume of sample than the SPR method.

Abstract
PURPOSE A new VEGF receptor fusion protein FP3 was shown to have promising antitumor potency better than Bevacizumab. Characterization of its immune response is essential to the safe and effective administration in clinical trials. In this study, both BIACORE and ELISA assays were employed to assess pre-clinical immunogenicity of FP3 in monkeys. EXPERIMENTAL DESIGN Serum samples from 20 rhesus monkeys were analyzed for the generation of anti-FP3 antibody after intravenous administration of three doses of FP3 (n = 6 per group) or buffer control (n = 2). Sera samples were obtained at 2, 4, 6, 8, 10 weeks after the first administration. RESULTS It showed BIACORE presented linear correlation with the dilution of anti-FP3 antibody and the results of ELISA. Two weeks after the initial FP3 injection, anti-FP3 antibody was detected in about 20% FP3-treated monkeys. The ratio of positive samples and the titer of antibody increased along with the FP3-treatment time. Six weeks following FP3 injection almost all the samples were anti-FP3 antibody positive. Moreover, the titer of anti-FP3 antibody but not the ratio of positive samples was also enhanced when the dose of FP3 was elevated. Furthermore, the immunoglobulin types and subclasses of anti-FP3 antibody serum components were mainly identified as IgG1 and IgG4, not IgM. Serum antibodies are characterized that they could not block FP3 binding to VEGF and were non-neutralizing. CONCLUSIONS Our data implied that proteins with full human sequences may also have the potential to induce immune response in rhesus monkeys, and BIACORE could be an effective approach to detect the immunogenicity of protein therapeutics in clinic.
