Pig Plaet Derived Growth Factor D (PDGFD) ELISA

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.

豬血小板衍生生長因子D(PDGFD)檢測盒另一片段類似Fc，隨后被分解成小分子多肽，無生物活性。　　IgM是由五個單體組成的五聚體，含10個重鏈和10個輕鏈，具有10個抗原結(jié)合價，由于空間位置的影響，只表現(xiàn)為五個抗原結(jié)合價。IgM分子量約為900000，IgG分子量約為150000。　　機(jī)體被微生物感染后，先產(chǎn)生IgM抗體，然后產(chǎn)生IgG抗體。經(jīng)過一段時間，IgM抗體量逐漸減少而消失，而IgG抗體可*存在，在疾病*后可持續(xù)數(shù)年之久。IgM抗體一般為保護(hù)性抗體，具有免疫性。因此IgM抗體的測定，對某些傳染病如甲型肝炎有較高的臨床診斷價值。
