TrypZean® is a recombinant, animal-free alternative to bovine or porcine trypsin. TrypZean® is produced in plants and has the same kinetics as native trypsin [1]. TrypZean® performs similar to bovine or porcine trypsin in a number of applications [2] [3].

Discounted rates are available for larger quantities. Please contact our Product Manager by email at or by phone at 805-215-9500 for a personalized price quote.
For quantities less than 1 gram, visit Sigma-Aldrich (Product No. T3568).TrypZean® provides the following advantages:

  • Certified animal-free, TrypZean® eliminates the risk of animal-source contaminants such as viruses and bovine spongiform encephalopathy (BSE).
  • TrypZean® is free of contaminants associated with animal source trypsin and therefore can be used in lower concentrations in some applications [4].

Commerical applications include:

  • Cell culture: Dissociation of attachment –dependent cell lines from plasticware in serum-free and serum-supplemented systems
  • Insulin manufacture: Cleaves “C” peptide from proinsulin to form active insulin
  • Vaccine manufacture: Cleaves undesirable antigens from cells used to produce vaccines in both human and veterinary vaccine manufacture.

1. What is Trypsin?
Trypsin is a protease derived from bovine or porcine pancreas that is used to digest other proteins. It specifically cleaves peptide bonds after basic amino acids such as lysine and arginine.
2. How is it used?
There are many market segments that use trypsin including bioprocessing, commercial cell culture, wound care, foods, and digestive aid.  It is used in the manufacture of several pharmaceutical proteins including insulin.
3. Is TrypZean® certified animal-free?
4. How can I order TrypZean®?
You can purchase TrypZean® directly from the Applied Biotechnology Website or from Sigma-Aldrich (Product No. T3568). If you would like to purchase more than 1 gram, please contact our Product Manager for TrypZean® for a personalized price quote by email at or by phone at 805-215-9500.
5. Do you provide a Certificate of Analysis?
Yes, each lot of TrypZean® comes with a Certificate of Analysis.
