Rantes Human Recombinant (CCL5)

Lyophilized powder at room temperature.

Rantes Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 68 amino acids and having a molecular mass of 7809.2 Dalton. The Rantes is purified by proprietary chromatographic techniques.
Amino Acid Sequence:SPYSSDTTPC CFAYIARPLP RAHIKEYFYT SGKCSNPAVV FVTRKNRQVC ANPEKKWVRE YINSLEMS.
Physical Appearance and Stability: Lyophilized Rantes although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution Rantes 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: Lyophilized from a 0.2um filtered concentrated solution in 50mM NaAc, pH 5.0, 100mM NaCl. 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 Rantes in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: The Rantes activity is determined by the chemoattract of human blood monocytes at a concentration between 1-10ng/ml corresponding to a Specific Activity of 100, 000-1, 000, 000IU/mg.
