The enzyme-linked immunosorbent assay (ELISA) (/ ɪˈlaɪzə /, / ˌiːˈlaɪzə /) is a commonly used analytical biochemistry assay, first described by Eva Engvall and Peter Perlmann in 1971. [1] The assay is a solid-phase type of enzyme immunoassay (EIA) to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the ligand to be measured ...
ELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detecting and quantifying soluble substances such as peptides, proteins, antibodies, and hormones. Other names, such as enzyme immunoassay (EIA), are also used to describe the same technology. In an ELISA, the antigen (target macromolecule) is immobilized on a solid surface (microplate) and then complexed ...
What is ELISA? ELISA is a common laboratory testing technique that detects and counts certain antibodies, antigens, proteins and hormones in bodily fluid samples. This includes blood, plasma, pee, saliva (spit) and cerebrospinal fluid (CSF). “ELISA” stands for “enzyme-linked immunosorbent assay.” Another name for it is an EIA test.
The enzyme-linked immunosorbent assay (ELISA) detects antigen-antibody interactions by using enzyme-labelled conjugates and enzyme substrates that generate colour changes. This review aims to provide an overview of ELISA, its various types, and its ...
An overview of ELISA: a review and update on best laboratory practices ...
Enzyme-linked immunosorbent assay (ELISA). The antigen or antibody is coated on solid surface such as in plastic tube or well of microtiter plate.
An enzyme conjugated with an antibody reacts with a colorless substrate to generate a colored reaction product. A number of enzymes have been employed for ELISA, including alkaline phosphatase, horseradish peroxidase, and B-galactosidase. Principle of ELISA ELISA is a plate-based assay technique.
