TB Ab ELISA Kit is most commonly used for the qualitative determination of human serum, plasma, and related liquid sample anti-Mycobacterium tuberculosis (TB-Ab).
ELISA based on the immunological reaction of the antigen, led by nine body-specific reaction with the enzyme substrate and efficient catalytic phase combine a highly sensitive test technology. Antigen and antibody reaction in a solid phase carrier ─ ─ polystyrene microtiter plate hole, each joined to the specificity of a reagent after incubation, by washing to remove excess free reactants, in order to ensure the test results and stability. In practical applications, different design, the specific method steps can be a variety. Namely: the indirect method for the detection of antibodies (Figure a) for the detection of antigen by double antibody sandwich (Figure b) and for the detection of small molecular antigen or hapten antigen competition law. Commonly used is the ELISA double antibody sandwich and indirect ELISA.
