Bio-Rad Introduces the ProteOn NLC Sensor Chip Application Guide

13 Sept 2007

Product news

Bio-Rad Laboratories, Inc., a multinational manufacturer and distributor of life science research products and clinical diagnostics, today announced the availability of Bio-Rad’s product application guide (bulletin 5449A), which describes the application of Bio‑Rad’s ProteOn™ NLC sensor chip for antibody-antigen, DNA-protein, and protein-protein interactions.

In this four-page application guide, researchers at the Weizmann Institute and the Technion in Israel demonstrate the determination of kinetic rate constants for three typical bimolecular model interactions. Using Bio-Rad’s ProteOn XPR36 protein interaction array system and NLC sensor chips, each of the three models studied use a simple two-step protocol consisting of the immobilization of one concentration of biotinylated ligand, followed by injection of six different concentrations of analyte. The results demonstrate the efficiency of the one-shot kinetics technique described in the introduction by V. Bronner, et al, in the paper entitled, “Rapid and efficient determination of kinetic rate constants using the ProteOn XPR36 protein interaction array system”, Bio-Rad bulletin 3172, published in 2006.

Supported by sensorgram and other graphic figures, the application guide contains a detailed introduction, methods description, results discussion, and a conclusion.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Lab-on-a-ChipLab-on-a-chip (LOC) technology uses microfluidic chips, such as microarrays, to perform biochemical assays on a small scale. Benefits of lab-on-a-chip include the small volume of sample required as well as the speed of analysis. In selecting lab-on-a-chip devices consider the assay, cost, reliability, sensitivity and signal to noise ratio.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.
