The superior replacement for trypsin

Gibco TrypLE reagents are highly purified, recombinant cell-dissociation enzymes that replace porcine trypsin. These reagents are ideal for dissociating attachment-dependent cell lines in both serum-containing and serum-free conditions, and can be directly substituted for trypsin without protocol changes.

TrypLE reagents are:

  • Gentle on cells—protect your cell’s surface proteins
  • Stable at room temperature—no need to freeze means they’re ready when you need them
  • Animal origin–free—important if you’re looking for a product without animal-derived components

TrypLE Express reagent outperforms trypsin in preserving cell-surface epitope expression

Jurkat cells were treated with 0.05% trypsin (A) or TrypLE Express reagent (B) for a period of up to 20 minutes. Cell-surface CD2 levels were then measured via flow cytometry with an APC-conjugated anti-CD2 monoclonal antibody. As demonstrated, cells treated with 0.05% trypsin show a clear time-dependent reduction in CD2 levels, those treated with TrypLE Express regent exhibit no measurable CD2 loss.

Flow cytometry analysis: cell dissociation from mouse CNS tissue

Flow cytometry is an invaluable part of the scientist’s toolbox in the field of cell biology, providing a wealth of information. In one study, different cell dissociation reagents were compared and their impact on cell viability and membrane protein integrity assessed. The authors concluded that dissociation with TrypLE reagent is efficient and preserves both cell viability and cell-surface protein epitope integrity.

Cell viability is better with TrypLE reagent than with Accutase reagent​. Dissociation time: 10min; Viability (%) +/- SEM​. Adapted from data shown in Stem Cells, 25:1560 (2007). doi:10.1634/stemcells.2006-0260

The CD24 epitope is retained with TrypLE whereas use of papain illustrates complete loss of the CD24 epitope (Adapted from data shown in Stem Cells, 25:1560 (2007). doi:10.1634/stemcells.2006-0260).
