Macrophage-Derived Chemokine (CCL22) Rat Recombinant

Lyophilized powder at room temperature.

CCL22 Rat Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 68 amino acids and having a molecular mass of 7.9kDa. The Rat CCL22 is purified by proprietary chromatographic techniques.
Amino Acid Sequence:GPYGANVEDS ICCQDYIRHP LPPRFVKEFY WTSKSCRKPG VVLITIKNRD ICADPRMLWV KKILHKLA.
Physical Appearance and Stability: Lyophilized MDC although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution MDC should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity: The protein was lyophilized from a 0.2um filtered concentrated solution in 1xPBS, pH7.4. Greater than 97.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Solubility: It is recommended to reconstitute the lyophilized MDC in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: Determined by its ability to chemoattract human activated lymphocytes using a concentration range of 10.0-100.0 ng/ml.
