MIG, a CXC chemokine, is produced by IFN-γ stimulated monocytes, macrophages and endothelial cells. It signals through the CXCR3 receptor. MIG selectively chemoattracts Th1 lymphocytes, and also exerts other activities, including inhibition of tumor growth, angiogenesis, and inhibition of colony formation of hematopoietic progenitors. Human MIG is active on murine cells. Recombinant Human MIG is an 11.7 kDa protein containing 103 amino acid residues, including the four highly conserved cysteine residues present in CXC chemokines.
Amino Acid Sequence
Determined by its ability to chemoattract human peripheral blood T lymphocytes using a concentration range of 10.0–100.0 ng/ml.
Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–0.5 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.
