Recombinant Murine MCP-2/CCL8 (rMuMCP-2/CCL8)

• Description:

  MCP-2 and MCP-3 are two recently identified monocyte chemotactic proteins produced by human MG-63 osteosarcoma cells. Both MCP-2 and MCP-3 are members of the C-C family of chemokines and share 62% and 71% amino acid sequence identity, respectively, with MCP-1. MCP-3 also shares 58% amino acid identity with MCP-2. Similarly to other C-C chemokines, all three MCP proteins are monocyte chemoattractants. In addition, the three MCPs can chemoattract activated NK cells as well as CD4+ and CD8+ T lymphocytes. All three cytokines have also been shown to attract eosinophils and induce histamine secretion from basophils.

• Endotoxin:

  Less than 1EU/g of rMuMCP-2/CCL8 as determined by LAL method.

• Purity:

  >97% by SDS-PAGE and HPLC analyses.

• Bioactivity:

  Fully biologically active when compared to standard. Determined by its ability to chemoattract human peripheral blood monocytes using a concentration range of 10.0-100.0 ng/ml, corresponding to a Specific Activity of > 1 x 104 IU/mg.

• Reconstitution:

  We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20C. Further dilutions should be made in appropriate buffered solutions.

• Molecular Weight:

  8.5 kDa, a single, non-glycosylated polypeptide chain containing 74 amino acids.

• Storage Conditions:

  This lyophilized preparation is stable for several weeks at 2-8C, but should be kept at -20C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20C to -70C. Avoid repeated freeze/thaw cycles.

• Appearance:

  Sterile Filtered White lyophilized (freeze-dried) powder.

• Formulation:

  Lyophilized from a 0.2m filtered concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.

• Host or Source:

  Escherichia coli.

• Recommended Usage:

  This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China
