Recombinant Human Migration Inhibitor Factor (rHuMIF)

Product Synonym Names
Migration Inhibitor Factor; human MIF; Human Migration Inhibitory Factor
Research Use Only
For Research Use Only. Not for use in diagnostic procedures.
Host
E Coli
Purity/Purification
>95% by SDS-PAGE and HPLC analyses.
Form/Format
Lyophilized from a 0.2mm filtered concentrated (1mg/ml) solution in PBS, pH 7.4.
Physical Appearance: Sterile FilteredWhite lyophilized (freeze-dried) powder.
Molecular Weight Information
Approximately 13 kDa, a monomeric, non-glycosylated polypeptide chain containing 117 amino acids.
Biological Activity
Fully biologically active measured by its ability to bind rhCD74 in a functional ELISA.
Endotoxin Level
Less than 1EU/mg of rHuMIF as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at <-20 degree C. Further dilutions should be made in appropriate buffered solutions.
Preparation and Storage
This lyophilized preparation is stable at 2-8 degree C, but should be kept at -20 degree C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 degree C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degree C to -70 degree C. Avoid repeated freeze/thaw cycles.
Other Notes
Small volumes of Migration Inhibitor Factor protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
Related Product Information for
Migration Inhibitor Factor protein
Human MIF consists of two á-helices and six -strands, four of which form a -sheet. The two remaining -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 have also been suggested to contain thiol-protein oxidoreductase activity. MIF has proinflammatory cytokine activity centered around aa's 49 - 65. On fibroblasts, MIF induces, IL-1, IL-8 and MMP expression; on macrophages, MIF stimulates NO production and TNF-á release folllowing IFN- 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% aa identical to mouse, bovine, porcine and rat MIF, respectively.
