Recombinant Mouse MIF

Description :
FAQ COA 已发表文献 Macrophage migration inhibitory factor(MIF or MMIF), also named asglycosylation-inhibiting factor (GIF),L-dopachrome isomerase, orphenylpyruvate tautomerase, is aproteinencoded by the MIFgene. It is released from white blood cells by bacterial antigen stimulation to trigger an acute immune response, or by glucocorticoids to counter-act the inhibitory effects of glucocorticoids on immune system. MIF is a homotrimer of which each subunit contains 115 amino acids. As mentioned above, MIF is involved in the innate immune response to bacterial pathogens and counter-acts the anti-inflammatory activity of glucocorticoids. Furthermore, it also plays a role as mediator in regulating the function of macrophages in host defense and has phenylpyruvate tautomerase and dopachrome tautomerase activity in vitro. Rat MIF is 99%, 90%, 89%, and 89% a.a. identical to human, murine, porcine and bovine, respectively.
