Description

The MCP proteins are members of the CC chemokine family that signal through CCR2 and, with the exception of MCP-1, other CCR receptors. The MCP proteins chemoattract and activate monocytes, activated T cells, basophils, NK cells, and immature dendritic cells. The MCP family cross-reacts across species. Recombinant Rat MCP-1 is a 14.0 kDa protein containing 125 amino acid residues, including the four highly conserved cysteine residues present in the CC chemokines.

Biological Activity

Determined by its ability to chemoattract human monocytes using a concentration range of 10.0–100.0 ng/ml.

Endotoxin

Endotoxin level is <0.1 ng/μg of protein (<1EU/μg).

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1–1.0 mg/ml. Do not vortex. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at –20°C to –80°C.

Storage/Expiration

 –20°C
