Recombinant Mouse MCP-3

Monocyte chemotactic protein-3 (MCP3) is a non-glycosylated polypeptide belonging to the the CC-Chemokines family that attracts monocytes and eosinophils, augments monocyte anti-tumor activity, and induces the release of gelatinase B. It also regulates protease secretion by macrophages. MCP3 can bind heparin.¹ MCP-3 is one of the most pluripotent chemokines since it activates all types of leukocytes.
MCP-3 may affect HIV-1 infection via inhibiting the binding of HIV envelope to CCR5.² MCP-3 has also been implicated in Multiple Sclerosis, allergic reactions and viral infections.^3,4,5

The biological activity of Mouse MCP-3 was determined by its ability to chemoattract 2-day cultured human monocytes (Matsushima, K. et al., 1989, J. Exp. Med. 169:1485) and its ability to chemoattract mouse BaF/3 cells transfected with hCCR2A. The expected ED₅₀ for these effects are typically 0.1 - 0.3 μg/ml and 0.5 - 2 μg/ml respectively.

Lyophilized

The predicted molecular weight of Recombinant Mouse MCP-3 is Mr 8.5 kDa.

8.5

This recombinant protein was lyophilized from a 0.2 μm filtered solution in 30% acetonitrile (CH₃CN) and 0.1% trifluoroacetic acid (TFA).

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
