Monocyte Chemotactic Protein-4 Human Recombinant ( CCL13 ) ( MCP 4 Human )

Data sheet

Formulation

The protein was lyophilized from a concentrated (1mg/ml) sterile solution in 20mM PB, pH 7.4, 130mM NaCl.

Solubility

It is recommended to reconstitute the lyophilized MCP-4 in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 96.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

Monocyte Chemotactic Protein-4 Human Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 75 amino acids and having a molecular mass of 8.6 kDa. The MCP-4 is purified by proprietary chromatographic techniques.

Protein Background

Chemokine (C-C motif) ligand 13 (CCL13 / MCP-4) is a small cytokine belonging to the CC chemokine family. The MCP-4 gene is located on human chromosome 17 within a large cluster of other CC chemokines. MCP-4 induces chemotaxis in monocytes, eosinophils, T

Expression host

Escherichia Coli.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized MCP-4 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution MCP-4 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
