(*)Complete precursor sequence shown, expressed chain highlighted

Optimized DNA sequence encoding Human MCP-2(CCL8) mature chain was expressed in Escherichia Coli.

Molecular weight:

Human MCP-2, generated by the proteolytic removal of the signal peptide
and propeptide and has a calculated molecular mass of approximately 9 kDa.

Recombinant MCP-2 is a disulfide-linked monomeric protein consisting of  77amino acid residue subunits and migrates as an approximately 9 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE.

>98%, as determined by SDS-PAGE and HPLC

Biological Activity:
The ED(50) was determined by the dose-dependent chemo-attraction of THP1 leukemic cells and was found to be ≤ 50 ng/ml, corresponding to a specific activity of > 5x 104 units/mg.

Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

MCP-1 was lyophilized from a 0.2 μm filtered 20mM PB solution pH 7.5, 100mM NaCl.

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.

The lyophilized protein is stable for at least 2 years from date of receipt at -20° 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.

Monocyte chemotactic protein MCP-2 is a C-C chemokine.It shares over 60% amino acid identity with MCP-1 and MCP- 3 and has about 30% identity with other C-C chemokines MIP-1 alpha, RANTES, and MIP-1 beta.MCP-2 is chemotactic for and activates a wide variety of inflammatory cells, and its spectrum of action on leukocytes is similar to that of MCP-3, including monocytes, T lymphocytes, NK cells, basophils, mast cells, and eosinophils, but differs from MCP-1, which is not active on eosinophils. MCP-2 has been proposed to interact with multiple C-C chemokine receptors, including those used by MCP- 1 and MCP-3. However, since leukocytes express a multiplicity of chemokine receptors with promiscuous binding and functional properties, it is difficult to identify the receptors used by a given ligand on these cells.
