TrypLE™ Express is an animal origin-free, recombinant enzyme used for dissociating a wide range of adherent mammalian cells, including CHO, HEK 293, A529, primary human keratinocytes, and embryonic stem cells. TrypLE™ Express cleaves peptide bonds on the C-terminal sides of lysine and arginine, and is a direct replacement for trypsin. Its exceptional purity increases specificity and reduces damage to cells that can be caused by other enzymes present in some trypsin extracts.

We offer a variety of TrypLE™ formulations for a range of cell culture applications.

Compared to trypsin and other dissociation reagents, Gibco® TrypLE™ Express is:

Gentle on cells

Room-temperature stable
Easy to use
Animal origin-free (AOF)

This TrypLE™ Express is modified as follows:


• Phenol Red


The formulation of TrypLE™ solutions is available, although we keep the enzyme concentration confidential.

Gentle On Cells
TrypLE™ Express' exceptional purity increases specificity due to the action of a single enzyme. This reduces damage caused by cleavage from enzymes present in some trypsin preparations and in other protease extracts.

Room-Temperature Stable
TrypLE™ Express is room-temperature stable and ready to use. TrypLE™ Express remains stable for 24 months at room temperature or 2–8°C, making storage and handling easy and convenient.

Easy to Use
TrypLE™ Express can be directly substituted for trypsin in existing protocols. In addition, dilution alone inactivates TrypLE™ Express, avoiding the need for trypsin inhibitors, such as FBS.

Animal Origin-Free (AOF)
Unlike porcine trypsin, TrypLE™ Express is free of animal-derived components.

cGMP Manufacturing and Quality System
