Better Antibody Screening: Improve Success, Reduce Costs, Reduce False Negatives
8 Sept 2013Screening hybridoma libraries for antibodies that bind to cell surface antigens is a critical bottleneck in the biologics discovery process. This time- and resource-intensive process often involves several sequential testing steps. This white paper discusses the multiple challenges contributing to this bottleneck, and provides solutions to overcome these issues that ultimately improve the antibody screening processes.

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.ELISAEnzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits.
