We stand by the quality of our products.

We measure our enzymatic activities using validated methods. Each order of our 10 and 20-donor CryostaX is accompanied by a lot-specific data sheet.

We calculate theoretical enzymatic activities from the characterization of individual donors, and achieve those activities in the finished pooled product. All CYPs are targeted for average activity levels (based on our human hepatocyte characterization database) to assure lot-to-lot consistency.
