Amino Acid Sequence: MPMFIVNTNV PRASVPDGFL SELTQQLAQA TGKPPQYIAV HVVPDQLMAF GGSSEPCALC SLHSIGKIGG AQNRSYSKLL CGLLAERLRI SPDRVYINYY DMNAANVGWN NSTFA

This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions

Purity

>95%, by SDS-PAGE

Endotoxin Level

Less than 1 EU/ug of MIF as determined by LAL method.

Predicted Molecular Mass

12.5 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Activity

MIF Protein is fully biologically active when compared to standard. The specific activity is determined by binding rhCD74 in a functional ELISA.

Background: MIF

Migration Inhibitory Factor (MIF) is a secreted protein without a cleavable signal sequence and is secreted via a specialized, nonclassical pathway. It is secreted by macrophages upon stimulation by bacterial lipopolysaccharide (LPS), or by M.tuberculosis antigens. MIF consists of two alpha-helices and six beta-strands, four of which form a beta-sheet. The two remaining beta-strands interact with other MIF molecules, creating a trimer. Structure-function studies suggest MIF is bifunctional with segregated topology. The N- and C-termini mediate enzyme activity (in theory). Phenylpyruvate tautomerase activity (enol-to-keto) has been demonstrated and is dependent upon Pro at position 1. Amino acids 50-65(a.a.) have also been suggested to contain thiol-protein oxidoreductase activity. MIF has proinflammatory cytokine activity centered around 49 - 65(a.a.). On fibroblasts, MIF induces, IL-1, IL-8 and MMP expression; on macrophages, MIF stimulates NO production and TNF-alpha release folllowing IFN-gamma activation. MIF apparently acts through CD74 and CD44, likely in some form of trimeric interaction. Human MIF is active on mouse cells. Human MIF is 90 %, 94 %, 95 %, and 90 % a.a. identical to mouse, bovine, porcine and rat MIF, respectively.
