Physical Appearance and Stability Lyophilized Activin-A, although stable at room temperature for 3 weeks, should be stored desiccated below -20C. Upon reconstitution, Activin-A should be stored at 4C for less than 7 days, and for future use below -20C. 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 The protein was lyophilized from a 0.2um filtered concentrated protein solution in PBS, pH 7.4. Greater than 98.0% as determined by SDS-PAGE.
Application
Solubility It is recommended to reconstitute the lyophilized Bone Morphogenetic Protein-4 in 0.5 sterile PBS, which can then be further diluted to other aqueous solutions.
Biological Activity
Shipping Format and Condition Lyophilized powder at room temperature.
