Technical Data
MCP2, Recombinant, Human (Macrophage/Monocyte Chemotactic Protein 2, Chemokine C-C Motif Ligand 8, CCL8, HC14, Monocyte Chemotactic Protein 2, Small Inducible Cytokine A8 Precursor, SCYA8, SCYA10)
Molecular Biology Storage: -20CShipping: Blue Ice
Recombinant corresponding to human MCP2 expressed in E. coli.

Molecular Weight:

Endotoxin: ~0.1ng/ug

Biological Activity:
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=30-100ng/ml. The optimal concentration should be determined for each specific application.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
Purity: ~95% (SDS-PAGE)
Concentration: Not determined
Form: Supplied as a lyophilized powder. BSA free. Reconstitute with sterile dH2O to 0.1-0.5mg/ml.
