よくあるご質問(FAQ)
How can I assess residual TrypLE reagent remaining after my downstream processing steps?
We offer the Residual TrypLE ELISA Kit (Cat. No. A6533101) that can specifically detect the recombinant protease (rProtease) in TrypLE reagent.
What enzymes do you recommend for passaging mesenchymal stem cells (MSC)?
We recommend using TrypLE Express Enzyme or TrypLE Select Enzyme for passaging mesenchymal stem cells (MSCs). The usage of trypsin will result in lower cell viability upon passage. TrypLE Express and TrypLE Select are defined, animal origin-free, and stable at both room and refrigerated temperatures.
Is there an upper limit for the amount of time cells can be incubated with TrypLE Express Enzyme, TrypLE Select Enzyme, or CTS TrypLE Select Enzyme for dissociation?
There is no upper limit for TrypLE enzyme incubation. You can incubate your cells with TrypLE longer to detach cells. 30-45 min at 37 degrees C will be usually fine. Or you can consider using TrypLE Select Enzyme (10X) (Cat. No. A1217701 or A1217702 or A1217703) or CTS TrypLE Select Enzyme (Cat. No. A4738001) depending upon the application.
For your TrypLE products, how does the enzyme get inactivated?
Our TrypLE enzymes are very gentle, and there is no need to use serum or individual proteins to inactivate the enzyme. The TrypLE enzyme activity is inactivated by dilution using the following procedure:
After cell dissociation, transfer the cell suspension to a 15-mL conical tube. Centrifuge at 100 x g for 5-10 min to remove residual enzyme activity. Discard the supernatant and resuspend the cell pellet in 2-5 mL of pre-warmed complete medium.

We describe a method to help overcome restrictions on the differentiation propensities of human pluripotent stem cells. Culturing pluripotent stem cells in dimethylsulfoxide (DMSO) activates the retinoblastoma protein, increases the proportion of cells in the early G1 phase of the cell cycle and, in more than 25 embryonic and induced ...
