CryostaX® Pooled Human Hepatocytes for Suspension

CryostaX® is the largest multi-donor pool available using a single-freeze process, designed to provide long-term consistent results, extensive characterization, the highest possible enzymatic activity, and on-demand custom-pooling.

Your suspension assays are faster and easier when you use CryostaX®

  • Patented single-freeze process to minimize cryoinjury
  • Simplified thawing procedure
  • Enhanced viability and yield
  • Extensive characterization
  • 10-or 20-donor lots available
  • Custom on-demand pooling at no additional charge (use form below)
  • Large lots for consistency between assays
  • High-quality data
  • Up-front pricing

Utilizing CryostaX® Pooled Human Hepatocytes for Suspension

CryostaX® features two different pool sizes, plus custom on-demand options (see form below) based on individual enzyme activities and/or donor demographics from over 200 potential donors. Whatever your study requires, XenoTech can meet your needs with a wide variety of pooled primary human hepatocytes ready for your in-house in vitro work.

Our patented format highlights our commitment to efficiency without sacrifice to quality; CryostaX® hepatocyte pellets go through one cryopreservation cycle rather than two (as is typical of traditional vial format), the thawing process is simplified to enable you to go from storage to assay in fewer steps, and our streamlined ordering process gives you all the information you need–including upfront pricing–to choose the perfect lots for your assays. 

Our hepatocyte expertise stems from decades of preparing these test systems for our own contract research. Utilizing the hepatocytes that we produce in our own contract studies allows an added level to quality control beyond the standard characterization that most hepatocytes vendors provide.

On-Demand Custom Pooling

An example of no-charge custom pooling of CryostaX® is shown below. By characterizing each individual donor, XenoTech enables you to pick from an extensive list of available tissue and design your own pools. By using the characterization data it is possible to determine a quick snapshot of the designed pool’s overall activities.
