Catalogue number
CYT-521
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, fused to His-tag at C-terminus, 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 chaincontaining 123 amino acidsand having a molecular mass of 13.5 kDa.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered lyophilized powder.
Formulation
Human MIF was lyophilized from a 1mg/ml solution containing PBS pH-7.4.
Solubility
It is recommended to reconstitute the lyophilized MIF in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized MIF although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution MIF 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 95.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Biological Activity
Measured by its ability to bind rhCD74 in a functional ELISA.
