Introduction

Cell culture is at the heart of modern life science, from drug discovery to vaccine production and regenerative medicine. To achieve consistent, reliable results, researchers need reagents that are not only effective but also safe and reproducible. Traditional porcine-derived trypsin has long been used for cell dissociation, but it presents challenges such as variability, contamination risks, and regulatory concerns.

Hzymes’ Trypsin, Recombinant Digestion (TrypLE-like, GMP Grade) is an animal-origin-free recombinant enzyme for dissociating a wide range of adherent mammalian cells, including CHO, HEK 293, A529, primary human keratinocytes, and embryonic stem cells.

GMP-grade recombinant trypsin provides animal-free cell dissociation for sensitive cell types including stem cells and primary cells. The Hzymes recombinant trypsin digestion reagent offers TrypLE-like performance with enhanced lot-to-lot consistency and regulatory documentation.

What is Recombinant Trypsin Digestion?

Recombinant trypsin digestion is a genetically engineered enzyme expressed in E. coli. Unlike traditional trypsin extracted from porcine pancreas, recombinant trypsin offers exceptional purity, consistency, and freedom from animal-derived components.

Hzymes developed its GMP-grade recombinant trypsin digestion reagent to meet the needs of biopharmaceutical manufacturing and advanced cell research. As a TrypLE-like alternative, it is optimized for both laboratory-scale and industrial applications, ensuring seamless integration into existing protocols.

Product Feature

1.     Gentle on cells—maintain cell health for reproducible results

Trypsin, Recombinant Digestion, like trypsin, cleaves peptide bonds on the C-terminal sides of lysine and arginine. However, Trypsin, Recombinant Digestion's exceptional purity increases specificity due to the action of a single enzyme. This reduces damage caused by cleavage from multiple enzymes in trypsin and other extracts.

2.     Easy to use—substitutes directly into existing protocols, with no inactivation required

Dilution alone inactivates trypsin and recombinant digestion, avoiding the need for trypsin inhibitors, such as FBS.

3.     Animal origin free (AOF)—pure, consistent, and effective

Activity unit: 25℃, pH 7.6, reaction system 3.2ml (1cm optical path). One trypsin unit (USP) is defined as the amount of trypsin that increases absorption value by 0.003 under 253nm through enzymolysis of BAEE per minute.
