WebELISA (which stands for enzyme-linked immunosorbent assay) is a technique to detect the presence of antigens in biological samples. An ELISA, like other types of immunoassays, relies on antibodies to detect a target antigen using highly specific antibody-antigen interactions. Basic ELISA principles (H2) In an ELISA assay, the antigen is ... Web2. Uncompetitive inhibition: the inhibitor binds to the enzyme in the presence of substrate in an inhibition equilibrium of the type E S + I ⇄ E S I. An uncompetitive inhibitor acts by decreasing the turnover number (corresponding to v max /[E]) while maintaining the proportion of enzyme molecules that are bound to substrate. WebEnzyme Inhibitors.
