Specific Activity of IL8 in chemotaxis of donor PBL neutrophils, threshold concentration of 25ng/ml corresponding to a Specific Activity of 40,000IU/mg.
Lyophilized from a concentrated (1mg/ml) solution in water containing 20mM sodium phosphate buffer pH-8.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Interleukin 8 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Lyophilized Interleukin-8 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution CXCL8 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.
