ELISA and Related Immunoassays
The Enzyme Linked Immunosorbent Assay (ELISA) is a very common, robust technique for detecting various analytes. It spawned a broad range of immunoassays that utilize either wash or no-wash workflows using colorimetric, fluorometric, luminometric, TRF or TR-FRET, AlphaScreen and AlphaLISA detection technologies. Some of these latter technologies utilize low volume analysis in 1536-well plates, yet ELISA performed in 96-well microplates remains the most commonly used immunoassay technique. The ELISA technique causes formation of specific immune complexes that are easily measured using BioTek’s single or multi-mode microplate readers. The basic “building blocks” of an ELISA reaction are:
Application Notes:
- Automation of a Novel Cell-Based ELISA for Cell Signaling Pathway Analysis
- Concentration and Detection of Low Levels of Escherichia coli O157:H7, Listeria monocytogenes 4b, and Salmonella enterica Typhimurium in High Organic Load Lettuce Wash
