SDF 1g Human

Data sheet

Formulation

SDF-1g protein was lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4.

Solubility

It is recommended to reconstitute the lyophilized SDF-1g in sterile 18M-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Purity

Greater than 96.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.

Description

SDF-1 gamma Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 99 amino acids and having a molecular mass of 11.6kDa.The SDF-1g is purified by proprietary chromatographic techniques.

Protein Background

SDF-1 (stromal cell-derived factor-1) is small cytokine belonging to the chemokine family that is officially designated Chemokine (C-X-C motif) ligand 12 (CXCL12). It is produced in two forms, SDF-1a/CXCL12a and SDF-1b/CXCL12b, by alternate splicing of th

Expression host

Escherichia Coli.

Reagent Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Stability

Lyophilized SDF-1g although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution SDF-1 gamma should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended t
