The specific activity as determined by its ability to chemoattract human peripheral blood monocytes at 100-150ng/ml corresponding to a Specific Activity of 6,667-10,000IU/mg.
The Rat SDF1B protein was lyophilized from a concentrated (1 mg/ml) sterile solution containing 20mM Phsophate buffer pH-7.4 and 0.15M NaCl.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized SDF-1b in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized SDF-1b although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution CXCL12 should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
