趋化因子配体 2 是属于 CXC 趋化因子家族的一种小细胞因子,也称为巨噬细胞炎症蛋白 2-α、生长调节蛋白 β 和 Gro oncogene-2。 CXCL2 在氨基酸序列上与相关趋化因子 CXCL1 有 90% 相同。 这种趋化因子由单核细胞和巨噬细胞分泌,对多形核白细胞和造血干细胞具有趋化作用。 CXCL2 的基因位于人类 4 号染色体上的其他 CXC 趋化因子簇中。 CXCL2 通过与称为 CXCR2 的细胞表面趋化因子受体相互作用来动员细胞。


GRO-Beta Mouse Recombinant also caled mouse MIP-2 produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 73 amino acids and having a molecular mass of 7849 Dalton.
The CXCL2 is purified by proprietary chromatographic techniques.


Escherichia Coli.

Physical Appearance

Sterile Filtered White lyophilized powder.


The protein was lyophilized from a concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.


It is recommended to reconstitute the lyophilized GRO-beta Mouse in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.


Lyophilized CXCL2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL2 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.


Greater than 97.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.

Amino acid sequence


Biological Activity

The Biological activity was determined by its ability to chemoattract total human neutrophils using a concentration range of 1.0-10.0 ng/ml, corresponding to a specific activity of 105-106units/mg.

Protein content

Protein quantitation was carried out by two independent methods:
1. UV spectroscopy at 280 nm using the absorbency value of 0.015 as the extinction coefficient for a 0.1% solution. This value is calculated by the PC GENE computer analysis program of protein sequences .
2. Analysis by RP-HPLC, using a standard solution of GRO-b as a Reference Standard.
