SpecificityThis assay has high sensitivity and excellent specificity for detection of KAL1. No significant cross-reactivity or interference between KAL1 and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between KAL1 and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman KAL1 ELISA Kit allows for the in vitro quantitative determination of KAL1 , 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: KAL1 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-KAL1 antibody and an KAL1-HRP conjugate. The assay sample and buffer are incubated together with KAL1-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the KAL1 concentration since KAL1 from samples and KAL1-HRP conjugate compete for the anti-KAL1 antibody binding site. Since the number of sites is limited, as more sites are occupied by KAL1 from the sample, fewer sites are left to bind KAL1-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The KAL1 concentration in each sample is interpolated from this standard curve.
