Key Properties
−| Source | Escherichia Coli |
|---|---|
| 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. |
| Protein Sequence | The sequence of the first five N-terminal amino acids was determined and was found to be Lys-Pro-Val-Ser-Leu |
| Purity | Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE. |
Storage & Handling
−| Storage | 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 |
|---|---|
| Form/Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Buffer/Preservatives | The CXCL12 protein was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives. |
| Disclaimer | For research use only |
