85-4496-64　Immunoglobulin A (IgA) BioAssay™ ELISA Kit (Human) 48Tests　351651

特徴

• Sample Type:Serum and plasma
• Intended Use:For the quantitative determination of human immunoglobulin A (IgA) concentrations in serum, plasma.
• Sensitivity:1.56ng/ml
• Range:0.25-1000ng/ml
• Specificity:This assay has high sensitivity and excellent specificity for detection of human IgA. No significant cross-reactivity or interference between human IgA and analogues was observed.
• Test Principle:This BioAssay™ employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for IgA has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IgA present is bound by the immobilized antibody. After removing any unbound substances, a Horseradish Peroxidase (HRP)-conjugated antibody specific for IgA is added to the wells. Following a wash to remove any unbound reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IgA bound in the initial step. The color development is stopped and the intensity of the color is measured.
