| Catalog # | M2750-18B2 | | Source | Recombinant corresponding to 75aa from human MCP4 expressed in E. coli. | | Molecular Weight | ~8.6kD | | Endotoxin | ~0.1ng/ug | | Biological Activity | Determined by measuring concentration dependent chemotaxis with human blood cells. A concentration range of 10-100ng/ml produces significant chemotaxis with human eosinophils. The optimal concentration should be determined for each specific application. MCP-4 is a b-chemokine (C-C chemokine). | | Storage and Stability | Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. 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 | ~8.6kD | | Purity | ~98% (SDS-PAGE, HPLC) | | Concentration | Not determined | | Form | Supplied as a lyophilized powder. BSA free. Reconstitute with sterile dH2O to 0.1-1mg/ml. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
