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 PBMCs were cultured with 0 to 1000ng/ml Human MIF. Production of IL-8 was measured via ELISA after 24 hours. The ED50 which was found to be 88-132ng/ml.
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.
