Intended UseHuman dLL4 ELISA Kit allows for the in vitro quantitative determination of dLL4 , 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: The kit is a sandwich enzyme immunoassay for in vitro quantitative measurement of dLL4 in human tissue homogenates, cell lysates and other biological fluids.
Principle of the Assay||The microtiter plate provided in this kit has been pre-coated with an antibody specific to dLL4. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to dLL4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain dLL4, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of dLL4 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
