It is recommended to reconstitute the lyophilized Beta Lactamase in sterile 18MΩ-cm H₂ O at a concentration of 100 µg/ml, which can then be further diluted to other aqueous solutions. The Beta Lactamase should be used in pH 7.0 - 8.0 and in temperature not higher then 45°C.

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