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

Compared to trypsin and other dissociation reagents, TrypLE Select is:

Gentle on cells—maintains cell health for reproducible results
Room-temperature stable—convenient to use
Easy to use—substitutes directly into existing protocols with no inactivation required
Animal origin free (AOF)—pure, consistent, and effective

This TrypLE Select is modified as follows:

With
• EDTA

Without
• Phenol Red

Gentle on cells
TrypLE Select, like trypsin, cleaves peptide bonds on the C-terminal sides of lysine and arginine. However, TrypLE Select'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.

Room-temperature stable
TrypLE Select is room-temperature stable and ready to use. TrypLE Select cell dissociation reagents remain stable for 24 months at room temperature or 2–8°C, making storage and handling easy and convenient.

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

Animal Origin Free (AOF)
Unlike porcine trypsin and other enzymes, TrypLE Select is free of animal-derived components and is formulated on dedicated animal origin-free equipment.

Product Intended Use
Customers using TrypLE Select in a manufacturing process, who have a submission with the FDA, may request a letter of authorization from us to reference our Type II Drug Master File (DMF).

cGMP Manufacturing and Quality System
TrypLE Select is manufactured at a cGMP compliant facility located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to ISO 13485 standards.

Frequently asked questions (FAQs)

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.

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.

Why are my cells not adhering when I transfer them to a new flask?

Trypsinize this type of cells for a shorter duration or use less trypsin or Gibco TrypLE Select or Gibco TrypLE Express Trypsin Replacement. After trypsinization dilute in 2 to 5 mL of cell culture growth medium transfer the cell suspension to 15 mL centrifuge tube. Centrifuge for 5-10 minutes at 100 x g. Discard the supernatant and suspend cell pellet in 2-5 mL fresh medium. Determine the count and seed the flask according to normal protocol and cell should adhere to the surface.

Do you have a non-animal-origin enzyme for cell dissociation?

Yes, the TrypLE products contain rProtease, a non-animal, trypsin-like enzyme used for the dissociation of attachment dependent cell lines. TrypLE enzyme has demonstrated the ability to dissociate cells cultured both in serum-free and serum-supplemented systems. The catalog numbers for TrypLE Select are 12563-011 (100 mL) and 12563-029 (500 mL). Some example catalog numbers for TrypLE Express include 12604-013 without Phenol red (100 mL) and 12605-010 with Phenol red (100 mL). Both formulations are also available in additional sizes. All these products are animal origin-free.
