SpecificityThis assay has high sensitivity and excellent specificity for detection of human beta-defensins 2. No significant cross-reactivity or interference between human beta-defensins 2 and analogues was observed.
Intended UseHuman DEFB4 ELISA Kit allows for the in vitro quantitative determination of DEFB4 , concentrations in serum, Plasma , tissue homogenates and Cell culture supernates and Other biological fluids.
StorageFor 5-7days:Store the whole kit at 4℃
For a Long time :Store the Substrate at 4℃, other reagent should store at -20℃.
Product Description specificalPrinciple of the Assay||This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for beta-defensins 2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any beta-defensins 2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for beta-defensins 2 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 beta-defensins 2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
