CXCL9 is a chemoattractant for activated T cells and possess angiostatic activity. Both CXCL9 and CXCL10 have been considered as important components for the anti-tumor activities of interferon-gamma (IFNgamma) and interleukin-12 in animal models. Mouse MIG is induced in THP-1 cells and in peripheral blood mononuclear cells by interferon-gamma but not by interferon-alpha or by lipopolysaccharide. Analysis of mouse and human genomic DNAs suggested that the Mumig and Humig genes are true mouse-human homologues.

Description:
Recombinant Mouse MIG (monokine induced by gamma-interferon ) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 105 amino acids and having a molecular mass of 12208 Dalton. Recombinant Mouse MIG is purified by proprietary chromatographic techniques.

Amino Acid Sequence:
The sequence of the first five N-terminal amino acids was determined and was found to be, Thr-Leu-Val-Ile-Arg.

Dimers and Aggregates:
Less than 1% as determined by silver-stained SDS-PAGE gel analysis.

Biological Activity:
MIG is fully biologically active when compared to standard. The Activity is calculated by the ability to chemoattract Human lymphocytes using a concentration of 0.1-1 ng/ml.

Endotoxin:
0.1ng/ug (IEU/ug) of Murine MIG.

Protein Content:
Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm .
2. Analysis by RP-HPLC, using a calibrated solution of Murine MIG as a Reference Standard.

Solubility:
It is recommended to reconstitute the lyophilized MIG in sterile 18M -cm H2O not less than 100g/ml, which can then be further diluted to other aqueous solutions.

Stability:
Lyophilized MIG although stable at room temperature for 3 weeks, should be stored desiccated below -180C. Upon reconstitution MIG should be stored at 40C between 2-7 days and for future use below -180C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles.

Molecular Weight:
12.21kD
Source: E. coli
Purity: 98% as determined by RP-HPLC, anion-exchange FPLC and/or reducing and non-reducing SDS-PAGE Silver Stained gel.
Concentration: ~1mg/ml
Form: Supplied as a lyophilized powder without additives.
