Physical Appearance and Stability Lyophilized APOE3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution APOE 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.
Formulation and Purity Lyophilized from a 0.2µm filtered solution in PBS. Greater than 95% as determined by SDS-PAGE.
Application
Solubility It is recommended to reconstitute the lyophilized APOE in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity Immobilized rHuApoE3 binds to rMuVLDLR with EC50 less than 0.4µg/ml.
Shipping Format and Condition Lyophilized powder at room temperature.
