Principle of Assay
Mouse Osteocrin ELISA Kit (A326791) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of mouse Osteocrin in serum, plasma, cell culture supernatant, cell or tissue lysate, and other biological fluids. A 96-well microtiter plate has been pre-coated with an antibody specific for Osteocrin. Standards and samples are added to the wells, where Osteocrin binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for Osteocrin is added to the wells. The detection antibody binds the captured Osteocrin to form an antibody-antigen-antibody sandwich complex. After further incubation and washing, HRP-Streptavidin conjugate is added to the wells. TMB substrate solution is then added to visualize the HRP enzymatic reaction. This produces a blue-coloured product that changes to yellow following addition of acidic stop solution. The intensity of the yellow colour is directly proportional to the amount of Osteocrin captured in each well. The concentration of Osteocrin is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
