Human HLA-DRA (HLA class II histocompatibility antigen, DR alpha chain) ELISA Kit

• Product Name Alternative:

  MHC class II antigen DRA; HLA-DRA; HLA-DRA1

• UniProt:

  P01903

• Reactivity:

  Human

• Field of Research:

  Immunology

• Assay Type:

  Sandwich

• Assay Principle:

  The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human HLA-DRA. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human HLA-DRA. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human HLA-DRA, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human HLA-DRA in the samples is then determined by comparing the OD of the samples to the standard curve.
