Viral MIP-2 is closely related to MIP-1α, show amino acid sequence similarity of about 41%. At the amino acid sequence level, Viral MIP-1 and Viral MIP-2 share 48% similarity. Viral MIP-1 and Viral MIP-2 are more closely linked to one another phylogenetically than to other human chemokines, signifying that they have gene duplication within the virus rather than by two independent gene aquisitions. Viral MIP-2 binds to the CCR3 chemokine receptor through which eotaxin and other β chemokines activate eosinophils. Viral MIP-2 activates and chemoattract human eosinphils.

MIP-2?Viral Recombinant produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 70 amino acids and having a molecular mass of 7.9 kDa.
The?MIP-2 is purified by proprietary chromatographic techniques.

Escherichia Coli.

Sterile Filtered White lyophilized (freeze-dried) powder.

Lyophilized from 1mg/ml solution containing 20mM Phospahte Buffer, pH 7.4 % 0.15M NaCl.

It is recommended to reconstitute the lyophilized CXCL2 Viral in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized MIP-2 Viral protein 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 (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.

Greater than 97.0% as determined by RP-HPLC & SDS-PAGE.
