Physical DescriptionSterile Filtered White lyophilized (freeze-dried) powder

FormulationThe protein (1mg/ml) was lyophilized with no additives

SolubilityIt is recommended to reconstitute the lyophilized Aprotinin in sterile water not less than 100ug/ml, which can then be further diluted to other aqueous solutions..

Store at -20^oC; Lyophilized form stable at room temperature for 3 weeks,should be stored desiccated below -20^oC .

Upon reconstitution, should be stored at 4^oC between 2-7 daysand for future use below -20^oC.
