WHAT IS AN ELISA?
ELISA is an acronym that stands for enzyme-linked immunosorbent assay. This technology is also sometimes referred to as EIA which stands for enzyme immunoassay.
ELISAs are a commonly used analytical technique to detect and quantify an analyte in a sample using antibodies that have highly specific binding affinities for the analyte.
In ELISA methodology, two essential components for quantification are highly specific antibodies that bind to their target and the immobilization of the analyte. The analyte or antibody is immobilized by attaching it to a surface, typically a 96-well microtiter plate or test tube, using a passive binding process. Quantification is achieved by using a purified analyte or antibody that is conjugated to an enzyme, often horse radish peroxidase (HRP), which binds to the immobilized target. Any non-specific interactions are eliminated by washing the surface. The final step involves exposing the enzyme to its substrate, resulting in a detectable signal, usually a color change. To halt the conversion of substrate to product, a solution may be added after a specific period of time. The signal from the sample is then compared to a standard curve to determine the concentration of the antigen present in the sample.
