1 answer-
This product is soluble in water at 50 mg/mL and may be filter sterilized. It is recommended to use a low protein binding filter membrane, such as PES, to prevent product retention in the filter. Solution stability has not been determined, however, Cold Spring Harbor protocols suggest that the filtered stock solution may be stored refrigerated or frozen.
