The MCP proteins belong to the CC chemokine family, and 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. Recombinant human MCP-1 is an 8.6 kDa protein containing 76 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines.
Human CCL2 expressed in E.coli
CAT# CSC-CTK0367-20 (20 μg); CAT# CSC-CTK0367-100 (100 μg)
Greater than 99% as determined by SDS-PAGE and HPLC analysis.
Determined by its ability to chemoattract human monocytes using a concentration range of 5.0- 20.0 ng/ml.
Less than 1 EU/μg.
Lyophilized protein with no additives.
Please centrifuge product briefly before opening the vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted rHu MCAF should be used immediately or stored long-term in undiluted working aliquots at -20°C. Please avoid repeated freeze / thaw cycles.
