SpecificityThis assay has high sensitivity and excellent specificity for detection of Ang1~7. No significant cross-reactivity or interference between Ang1~7 and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between Ang1~7 and all the analogues, therefore, cross reaction may still exist in some cases.
Intended UseHuman ANG (1 7) ELISA Kit allows for the in vitro quantitative determination of ANG (1 7) , 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 specificalIntended Uses: This Ang1~7 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human Ang1~7. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
Principle of the Assay||Ang1~7 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-Ang1~7 antibody and an Ang1~7-HRP conjugate. The assay sample and buffer are incubated together with Ang1~7-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 Ang1~7 concentration since Ang1~7 from samples and Ang1~7-HRP conjugate compete for the anti-Ang1~7 antibody binding site. Since the number of sites is limited, as more sites are occupied by Ang1~7 from the sample, fewer sites are left to bind Ang1~7-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The Ang1~7 concentration in each sample is interpolated from this standard curve.
