| Description | Stromal Cell-Derived Factor-1 beta Feline Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 72 amino acids and having a molecular mass of 8526 Dalton. The SDF-1b is purified by proprietary chromatographic techniques. |
| Uniprot Accesion Number | O62657 |
| Amino Acid Sequence | KPVSLSYRCP CRFFESHVAR ANVKHLKILN TPNCALQIVA RLKNNNRQVC IDPKLKWIQE YLEKALNKRF KM. |
| Source | Escherichia Coli. |
| Physical Appearance and 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. |
| Formulation and Purity | The protein was lyophilized from a concentrated (1 mg/ml) sterile solution containing no additives. Greater than 97.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
| Application | |
| Solubility | It is recommended to reconstitute the lyophilized SDF-1b in sterile 18MO-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
| Biological Activity | The specific activity as determined by its ability to chemoattract human peripheral T cells stimulated with IL-2 and PHA in a concentration range from 10-75 ng/ml corresponding to a Specific Activity of 13,334-100,000IU/mg. |
| Shipping Format and Condition | Lyophilized powder at room temperature. |
| Usage Statement | Our products are furnished for LABORATORY RESEARCH USE ONLY. The product may not be used as drugs, agricultural or pesticidal products, food additives or household chemicals. |
