Monokine induced by Interferon-g (MIG) is a member of the a (CXC) family of chemokines. It is produced by lymphokine activated macrophages, IFN-g-treated peripheral blood monocytes, IFN-g-treated primary glial cells of the central nervous system. MIG is a chemoattractant for activated T lymphocytes and tumor-infiltrating lymphocytes. The mouse mature protein contains 105 amino acid residue and migrates with an apparent molecular mass of 12 kDa. MIG has an extended C-terminus containing greater than 50% basic amino acid residues. The C-terminus is prone to proteolytic cleavage resulting in size heterogeneity. MIG binds to CXCR3 receptor which is highly expressed in IL-2-activated T cells..
Mouse Cxcl9 expressed in E.coli
A DNA sequence encoding the mature mouse MIG protein sequence was expressed in E. coli.
CAT# CSC-CTK0030-10 (10 μg); CAT# CSC-CTK0030-50 (50 μg)
Greater than 97% as determined by SDS-PAGE and visualized by silver stain
Activity was determined by ability to chemoattract human lymphocytes cultured in the presence of IL-2 for 14 - 21 days, or chemotaxis of CXCR3-transfected mouse BAF/3 cells. The ED50 for these effects were typically 0.1 - 0.3 μg/mL, or 0.1 – 0.5 μg/mL, respectively.
Endotoxin level less than 0.1 ng per 1 μg of the cytokine as determined by the LAL method.
Lyophilized from a 0.2 μm filtered solution in 30% CH3CN and 0.1% TFA containing 50 μg of bovine serum albumin per 1 μg of cytokine.
It is recommended that sterile PBS containing at least 0.1% human serum albumin or bovine serum albumin be added to the vial to prepare a stock solution of no less than 10 μg/mL.
Storage & Stability
Lyophilized samples are stable for greater than six months at -20°C to -70°C. Reconstituted mouse MIG/CXCL9 can be stored under sterile conditions at 2°C to 4°C for one month or at -20°C to -70°C for three months without detectable loss of activity. Avoid repeated freeze-thaw cycles.
