Source

Biotinylated Human MIF, His,Avitag (MIF-H82E7) is expressed from human 293 cells (HEK293). It contains AA Pro 2 - Ala 115 (Accession # P14174-1).

Predicted N-terminus: Pro 2

Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 16.0 kDa. The protein migrates as 20 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

Protein Ratio

Passed as determined by the SABA assay / HABA assay / binding ELISA.

Purity

>90% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in 25 mM MES, 500 mM NaCl, pH6.5 with trehalose as protectant.

バックグランド

Macrophage migration inhibitory factor(MIF) is also known as Glycosylation-inhibiting factor(GIF), L-dopachrome isomerase, L-dopachrome tautomerase, Phenylpyruvate tautomerase. Interacts with CXCR2 extracellular domain, CD74 extracellular domain, COPS5 and BNIPL. The expression of MIF at sites of inflammation suggests a role as mediator in regulating the function of macrophages in host defense. Counteracts the anti-inflammatory activity of glucocorticoids. Has phenylpyruvate tautomerase and dopachrome tautomerase activity (in vitro), but the physiological substrate is not known. It is not clear whether the tautomerase activity has any physiological relevance, and whether it is important for cytokine activity.
