Recombinant Staphylococcal Protein-A 33.4kDa

Lyophilized SPA although stable at room temperature for 3 weeks, should be stored desiccated below -18 °C. Upon reconstitution SPA 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.
