Principio di kit
Mouse Short Chain Fatty Acids (ScFA) ELISA Kit (A326877) employs the competitive enzyme immunoassay technique for the quantitative measurement of mouse Short Chain Fatty Acids (ScFA) in serum, plasma, cell culture supernatant, cell or tissue lysate, and other liquid samples. The 96-well microtiter plate has been pre-coated with Short Chain Fatty Acids (ScFA) antigen. During the incubation, Short Chain Fatty Acids (ScFA) present in the samples or standards competes with the fixed amount of immobilized Short Chain Fatty Acids (ScFA) for binding sites on the Biotinylated Anti-Short Chain Fatty Acids (ScFA) Antibody. The more Short Chain Fatty Acids (ScFA) present in a sample or standard, the less Biotinylated Anti-Short Chain Fatty Acids (ScFA) Antibody that binds to the plate. Following incubation, unbound Biotinylated Anti-Short Chain Fatty Acids (ScFA) Antibody is removed by washing, and an HRP-Streptavidin conjugate is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is then used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is inversely proportional to the amount of Short Chain Fatty Acids (ScFA) present in each sample or standard. The concentration of Short Chain Fatty Acids (ScFA) can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
