Sterile Filtered White lyophilized (freeze-dried) powder.
Purity
Greater than 98.0% as determined by(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Solubility (25°C)
It is recommended to reconstitute the lyophilized EMAP-II in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Determined by the apoptotic effect on MCF-7 cells using a concentration of 20-30 ng/ml.
Storage
Stability: Lyophilized EMAP-II although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution EMAP-II should be stored at 4°C between 2-7 days and for future use below -18°C.Please prevent freeze-thaw cycles
Buffer/Preservatives
Lyophilized from a concentrated (1mg/ml) solution in water containing 20mM sodium Phosphate buffer pH=7.5 and 130mM sodium chloride.
