Agrin (AGRN) BioAssay(TM) ELISA Kit (Rat)

Sample Type:, Serum, plasma, tissue homogenates and cell lysates, Intended Use: For the quantitative determination of rat agrin (AGRN) concentrations in serum, plasma, tissue homogenates and cell lysates. Sensitivity: 19.5pg/ml, Range: 78-5000pg/ml, Specificity: This assay has high sensitivity and excellent specificity for detection of rat AGRN. No significant cross-reactivity or interference between rat AGRN and analogues was observed. Test Principle: This BioAssay(TM) employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for AGRN has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any AGRN present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for AGRN is added to the wells. After washing, avidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of AGRN bound in the initial step. The color development is stopped and the intensity of the color is measured.
