Catalogue Number | CYT-596 |
Synonyms | Phenylpyruvate tautomerase, Glycosylation-inhibiting factor, GIF, MMIF, MIF. |
Introduction | The cytokine Macrophage migration inhibitory factor (MIF) has been identified to be secreted by the pituitary gland and the monocyte/macrophage and to play an important role in endotoxic shock. MIF has the unique property of being released from macrophages and T cells in response to physiological concentrations of glucocorticoids. The secretion of MIF is tightly regulated and decreases at high, anti-inflammatory steroid concentration. |
Description | MIF human Recombinant was cloned into an E.coli expression vector and was purified to apparent homogeneity by using conventional column chromatography techniques. Macrophage Inducing Factor Human Recombinant is a single, non-glycosylated, polypeptide chain containing 115 amino acids and having a molecular mass of 12.5 kDa. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Biological Activity | Human MIF biological activity was measured in an agarose microdroplet assay usinghuman U937 cells astargets.The optimal range of activity found for human MIF in this assay was 500-1,000ng/ml corresponding to a specific activity of 1,000-2,000IU/mg. |
Formulation | MIF-Protein was lyophilized from 10mM sodium phosphate buffer pH-7.5. |
Solubility | It is recommended to reconstitute the lyophilized MIF-Protein in sterile 18MΩ-cm H2O at a concentration between 0.1mg-1mg per 1ml. |
Stability | Lyophilized MIF-protein although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution MIF-protein should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. |
Purity | Greater than 97.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
