Comparison vs. individual donors

CryostaX was designed to provide long-term, consistent results at the greatest value. XenoTech’s large lots lower lot-to-lot variance compared to individual donor samples. Also, the preparation of the pellets allows for future customisation of pools “on demand.”














This chart compares the mean of CYP activities from 63 individual human donor lots of cryopreserved hepatocytes versus the CryostaX™ pool of 10. Individual lots were each measured in triplicate. The error bars show the extent of inter-individual variance of donors and the inter-assay variance of the CryostaX pool. CryostaX™ enzymatic activities were each measured in triplicate on three separate days using XenoTech’s validated LC/MS/MS methods.
