Principle of Assay
Human CHMP1A ELISA Kit (A335099) is a 4 hour sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human CHMP1A 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 CHMP1A. Standards and samples are added to the wells, where CHMP1A binds to the immobilized capture antibody. Following incubation, unbound components are removed by washing and a biotinylated detection antibody specific for CHMP1A is added to the wells. The detection antibody binds the captured CHMP1A 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 CHMP1A captured in each well. The concentration of CHMP1A is calculated by reading the absorbance at 450 nm and comparing the values with the standard curve.
