ELISAn.

Brit.

/ɪˈlʌɪzə/, U.S.

/ᵻˈlaɪzə/

Forms: 1900s– Elisa, 1900s– ELISA.

Origin: Formed within English, as an acronym. Etymon: English enzyme-linked immunosorbent assay.

Etymology: Acronym < the initial letters of enzyme-linked immunosorbent assay.

Biochemistry.

A type of sensitive, quantitative immunoassay utilizing an enzyme which produces a measurable change in the colour or other attribute of a substrate. Frequently attributive, esp. in ELISA test.In standard ELISA tests, antigens (or antibodies) attached to a solid surface are used to bind the relevant antibodies (or antigens) in the test solution. These antigen-antibody complexes are detected by measuring the activity of an enzyme (esp. horseradish peroxidase) which is bound to another antibody. ELISA tests are typically used to screen for viral and other infectious diseases.
