Enzyme-linked immunosorbant assay

Enzyme Linked Immuosorbent Assay; this is a screening test that is done for HIV infection as well as for other types of things; in the case of HIV, the ELISA must be confirmed by further testing (see "Western Blot") before the diagnosis of HIV is made

Enzyme-linked immunosorbent assay, a test used to detect antibodies against HIV in blood samples.

a blood test that detects antibodies based on a reaction that leads to a color change in the test tube. The HIV ELISA is commonly used as the initial screening test because it is relatively easy and inexpensive to perform. Because the HIV ELISA is designed for the greatest sensitivity : that is, it detects all persons with HIV antibodies as well as some who don't have them (false positives) : a positive HIV ELISA test must be confirmed by a second, more specific test such as an HIV Western Blot.

enzyme-linked immunosorbent assay. An immunological technique used for the quantitation of antigen or antibody in a sample such as blood plasma or serum. In the assay, enzyme-labeled antigen or antibody is bound to a solid surface (such as beads, tubes, or microplate wells). After addition of the sample and a substrate, the presence of the desired antigen, antibody, or antigen-antibody complex is indicated by a color change based on a reaction of the enzyme with the substrate.

ELISA is the abbreviation for "Enzyme-Linked Immunosorbent Assay" which is a highly sensitive technique for detecting and measuring antigens (allergens) in a solution. The solution is run over a surface to which immobilized antibodies specific to the antigen being measured have been attached. If the antigen is present, it will bind to the antibody layer, and then its presence is verified and visualized with an application of antibodies that have been tagged in some way.

immunological method which can be used for the detection of (known) GMOs in foods and other products. While PCR (see below) detects the modified gene(s) in a GMO directly, the ELISA method uses antibodies to detect the protein(s) that are expressed by the modified gene(s). This method only works if the GMO in question is known and if a suitable antibody is available.

enzyme-linked immunosorbent assay. Immunological test that uses an enzyme-mediated reaction as an indicator of an antigen-antibody reaction

An acronym for Enzyme Linked Immuno Sorbent Assay. The basis of this test is the antigen-antibody reaction. The attribute being tested for competes with other antibodies for binding sites in microwells. After a timed incubation period, the microwells are washed out, chromagen is added which will react colour-wise with the other antibodies. A specific period of time is allowed for colour development, a stop solution is added and the optical density of each well is read by a spectrophotometer. In most cases a multiple regression analysis is run on the results to determine actual values in the standards and samples.

(enzyme-linked immunosorbent assay). This is a laboratory test method to analyze blood for the presence and the amount of antibodies in the woman to DNA, phospholipids, and other things. The test tubes are coated with the substance such as the phospholipid. Then the serum to be tested is added. If there are antibodies in the serum against the phospholipid, they attach and in the process of attachment a color (dye) is released that turns the fluid in the test tube a different color. The intensity of the color tells you how high the immunity is (how much antibody is present).

Used to define antigenic specificity. Sample antibodies and enzyme-labeled antibodies compete for binding to an antigen or antigen-coated plate.

Used to screen for proteins. Sample antibodies (referred to as primary antibodies) bind to an antigen or antigen-coated plate. Another antibody (referred to as secondary antibody) is then added which binds to the first antibody and the amount of sample is detected by enzymatic detection.
