This product is not a sterile preparation. If the intended use, such as in cell culture, requires a sterile environment, then the stock solution would require filter sterilization. Typically, this is achieved by filtration through a 0.22 um membrane. Alternatively, product S9133 is a γ-irradiated, sterile powder. When reconstituted aseptically using sterile water, this product may be added directly to culture medium.
