Why does single freeze make a difference?

Hepatocytes are damaged by the freezing and thawing process. XenoTech’s unique, patent-pending process used to prepare CryostaX, eliminates the need for the second freeze used in conventional pooling methods, thus minimising cryoinjury and preserving enzymatic activity.

You are assured of the highest quality available for dependable results.
