Mouse MIF (Macrophage Migration Inhibitory Factor) ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Mouse MIF. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse MIF. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Mouse MIF, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Mouse MIF in the samples is then determined by comparing the OD of the samples to the standard curve. Protein Function: Pro-inflammatory cytokine involved in the innate immune response to bacterial pathogens (By similarity). The expression of MIF at sites of inflammation suggests a role as mediator in regulating the function of macrophages in host defense (By similarity). Counteracts the anti-inflammatory activity of glucocorticoids (By similarity). Has phenylpyruvate tautomerase and dopachrome tautomerase activity (in vitro), but the physiological substrate is not known (PubMed:10933783, PubMed:16780921, PubMed:19188446). It is not clear whether the tautomerase activity has any physiological relevance, and whether it is important for cytokine activity (PubMed:10933783, PubMed:16780921, PubMed:19188446) [The Uniprot Consortium]
