IgA, Human, BioAssay? ELISA Kit

£1,005.00 96 Tests

Test Principle:
The Human IgA ELISA kit is based on the binding of human IgA in samples to two antibodies, one immobilized on the microtiter wells, and the other conjugated to horseradish peroxidase (HRP) enzyme. After a washing step, chromogenic substrate is added and color is developed by the enzymatic reaction of HRP on the TMB substrate, which is directly proportional to the amount of IgA present in the sample. Stopping Solution is added to terminate the reaction, and absorbance at 450nm is then measured using an ELISA microtiter well reader. The concentration of IgA in samples and control is calculated from a curve of standards containing known concentrations of IgA.
