一般說明

Macrophage migration inhibitory factor (MIF) is a small secreted protein that can act as a pleiotropic pro-inflammatory cytokine as well as an enzyme. MIF pro-inflammatory activity can be initiated by signaling through cluster of differentiation 74 and 44 (CD74 and CD44), resulting in the secretion of tumor necrosis-α (TNF-α), interleukins-1, -6, -8, and various matrix metalloproteinases (MMPs). The gene encoding this protein is localized on human chromosome 22q11.23. Insect cell derived recombinant MIF is a 15kDa protein containing 124 amino acid residues, including an N-terminal His-tag.

生化/生理作用

The enzymatic activity of macrophage migration inhibitory factor (MIF) is characterized by its ability to act as a tautomerase, capable of catalyzing the keto to enol isomerization of keto-phenylpyruvate and L-dopachrome. It appears as though MIF catalytic activity is dependent upon a trimeric configuration and a free N-terminal proline residue.

重構

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
