Stromal Cell Derived Factor-1 Beta Human Recombinant (CXCL12)
| 目录号 | AP5769 |
|---|---|
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | The CXCL12 protein was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives. |
| Protein biological activity | The specific activity as determined by its ability to chemoattract human peripheral T cells activated with PHA and IL-2 using a concentation of 20-80ng/ml corresponding to a Specific Activity of 12,500-50,000IU/mg. |
| Amino acid sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Lys-Pro-Val-Ser-Leu. |
| Uniprot ACC# | P48061 |
| Purity | Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Solubility | It is recommended to reconstitute the lyophilized Stromal Cell-Derived Factor-1b in sterile 18M??-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Stability | Lyophilized SDF-1b although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CXCL12 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Source | Escherichia Coli. |
| Synonyms | SDF-1, CXCL12, Pre-B cell growth-stimulating factor, PBSF, hIRH, chemokine (C-X-C motif) ligand 12, SDF1, SDF1B, TPAR1, SCYB12, SDF-1b, TLSF-b. |
| Transportation method | Shipped at Room temp |
