Sterile Filtered White lyophilized （freeze-dried） powder. The protein was lyophilized from a concentrated solution （1mg/ml） containing 10mM Tris-HCl and 1mM EGTA. It is recommended to reconstitute the lyophilized CASQ2 in sterile 18M?-cm H2O not less than 100ug/ml， which can then be further diluted to other aqueous solutions.
保存建议
Lyophilized CASQ2 although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution CASQ2 should be stored at 4℃ between 2-7 days and for future use below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles.
