Increase Sensitivity in No-Wash Assays Using Confocal Imaging

15 Feb 2019

Screening of hybridoma supernatants for antibodies directed against cell-surface antigens is an important step in the discovery and development of antibodies for vaccines or therapeutic use. The sensitivity of these assays is increased by taking advantage of the optical properties of confocal imaging such as utilizing the narrow depth of field to acquire high signal-to-background, crisp images with no out of focus light creating image blur.

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.High-Content ScreeningHigh-content screening (HCS), also known as high-content analysis (HCA), is a high-throughput technique used in drug discovery to identify substances that alter the phenotype of cells. HCS uses fluorescent microscopic imaging and automated image analysis to investigate cellular events such as apoptosis, cell viability, GPCR activation, oxide production, neurite outgrowth, and cell signaling.
