|Alternative Names||C-X-C motif chemokine 9, Gamma-interferon-induced monokine, Monokine induced by interferon-gamma, Small-inducible cytokine B9, CMK, HuMIG, SCYB9, CXCL9|
|Description||MIG (CXCL9) protein belongs to the family of chemotactic cytokines known as chemokines. The synthesis of MIG is specifically induced in macrophages and in other cells by IFN-gamma.Human neutrophils produce mig in response to IFN-gamma in combination with either TNF-alpha or bacterial lipopolysaccharides and this response is blocked by IL-10 and IL-4. MIG is a chemoattractant for stimulated but not resting T cells, however it is not active on neutrophils or monocytes.|
|Molecular Weight||11.0 kDa|
|Endotoxin Level||<1.0 EU/μg of recombinant protein as determined by the LAL method.|
|Purity||>95% as determined by SDS-PAGE|
|Bioactivity||Determined by its ability to chemoattract human peripheral blood T lymphocytes using a concentration range of 10-80 ng/mL.|
|Formulation||Lyophilized from 1.0 mg/mL solution in 25 mM NaCl 10 mM PB pH 7.0.|
|Reconstitution||A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.|
|Storage||The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.|
|Usage||For research use only. Not for diagnostic or therapeutic use.|
· Endotoxin is generally measured in Endotoxin Units per milliliter (EU/mL).
· For recombinant proteins: EU is reported per microgram of protein.
· One EU = 0.1-0.2 ng endotoxin/µg of protein.
· At abm, we do the LAL chromogenic assays that can detect down to 0.01 EU/ml.
