| Monocyte Chemotactic Protein-2 Human Recombinant (CCL8), MCP 2 Human, 10ug |
Description
Monocyte Chemotactic Protein-2 Human Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 76 amino acids and having a molecular mass of 8904 Dalton.
The MCP2 is purified by proprietary chromatographic techniques.
Amino acid sequence
The sequence of the first five N-terminal amino acids was determined and was found to be Gln-Pro-Asp-Ser-Val.
Biological Activity
The biological activity was determined by measuring the dose dependent mobilization of intracellular calcium (calcium flux) with human THP-1 cells. Significant calcium mobilization is observed with 500ng/mL of recombinant human MCP-2. Human MCP-2 also induces dose dependent chemotaxis of human THP-1 cells with an ED50=30-100 ng/mL corresponding to a Specific Activity of 10,000-33,334IU/mg.
The protein was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Purity
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
Solubility
It is recommended to reconstitute the lyophilized Monocyte Chemotactic Protein-2in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Source
Escherichia Coli.
Stability
Lyophilized MCP2 although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CCL8should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
