TrypLE Express cleaves peptide bonds on the C-terminal sides of lysine and arginine, and is a direct replacement for trypsin.
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:
With
• Phenol Red
