ELISA results using S-OIV A neuraminidase antibody at 1 μg/ml to probe the immunogenic and the corresponding seasonal influenza A neuraminidase peptides at 50, 10, 2, and 0 ng/ml. Because the ELISA can be performed to evaluate either the presence of antigen or the presence of antibody in a sample, it is a useful tool for determining serum antibody concentrations (such as with the HIV test[3] or West Nile Virus). It has also found applications in the food industry in detecting potential food allergens such as milk, peanuts, walnuts, almonds, and eggs.[4] ELISA can also be used in toxicology as a rapid presumptive screen for certain classes of drugs. The ELISA was the first screening test widely used for HIV because of its high sensitivity. In an ELISA, a person's serum is diluted 400-fold and applied to a plate to which HIV antigens are attached. If antibodies to HIV are present in the serum, they may bind to these HIV antigens. The plate is then washed to remove all other components of the serum. A specially prepared "secondary antibody" — an antibody that binds to other antibodies — is then applied to the plate, followed by another wash. This secondary antibody is chemically linked in advance to an enzyme. Thus, the plate will contain enzyme in proportion to the amount of secondary antibody bound to the plate. A substrate for the enzyme is applied, and catalysis by the enzyme leads to a change in color or fluorescence. ELISA results are reported as a number; the most controversial aspect of this test is determining the "cut-off" point between a positive and a negative result. A cut-off point may be determined by comparing it with a known standard. If an ELISA test is used for drug screening at workplace, a cut-off concentration, 50 ng/mL, for example, is established, and a sample that contains the standard concentration of analyte will be prepared. Unknowns that generate a signal that is stronger than the known sample are "positive." Those that generate weaker signal are "negative." Doctor Dennis E Bidwell and Alister Voller created the test.
乳铁传递蛋白/乳铁蛋白抗体IgG(LF/LTF Ab-Ig)另一片段类似Fc,随后被分解成小分子多肽,无生物活性。 IgM是由五个单体组成的五聚体,含10个重链和10个轻链,具有10个抗原结合价,由于空间位置的影响,只表现为五个抗原结合价。IgM分子量约为900000,IgG分子量约为150000。 机体被微生物感染后,先产生IgM抗体,然后产生IgG抗体。经过一段时间,IgM抗体量逐渐减少而消失,而IgG抗体可*存在,在疾病*后可持续数年之久。IgM抗体一般为保护性抗体,具有免疫性。因此IgM抗体的测定,对某些传染病如甲型肝炎有较高的临床诊断价值。
