Trypsin (1X)

Product Overview


Trypsin is a proteolytic enzyme that is used to detach cells from an adherent substrate, and is the most frequently used member of the serine family. Trypsin is produced from proenzyme, trypsinogen secreted by exocrine cells of pancreas; Trypsin acts on C-terminal side of Lysine or Arginine.  Long term incubation with high trypsin concentration damages cells by striping cell surface proteins, eventually killing the cells.

About Trypsin (1X)

What is Trypsin?

Trypsin is a proteolytic enzyme that is used to detach cells from an adherent substrate, and is the most frequently used member of the serine family. Trypsin is produced from proenzyme, trypsinogen secreted by exocrine cells of pancreas; Trypsin acts on C-terminal side of Lysine or Arginine.  Long term incubation with high trypsin concentration damages cells by striping cell surface proteins, eventually killing the cells.

Trypsin Storage and Handling

Trypsin products are supplied in gamma irradiated, sterile PETG or PETE bottles and are available in customizable sterile LDPE bags. Biologos recommends that Trypsin products be stored frozen at a temperature range of -50C to -100C. Always use aseptic techniques when handling the Trypsin Solutions.

Trypsin products are shipped frozen by next day air in temperature-controlled LTL freight delivery trucks.

Trypsin Uses

Trypsin is a proteolytic enzyme and a member of the serine protease family, that is used to detach cells from an adherent substrate. 

Trypsin Concentrations and Formulations

Biologos offers Trypsin products in multiple formulations and concentrations (see below), customizable container sizes (100 ml, 500 ml, 1 Liter, 20 Liter, etc.) and varied container types (sterile bottles, sterile bags, etc.).  Based on the application and cell types, trypsin is produced with various constituents and at various concentration. The most common variations are:
  • EDTA (disodium ethylenediaminetetraacetic acid) - To weaken interactions, EDTA is frequently included with Trypsin which chelates the divalent cations (Ca2+, Mg 2+).
  • Phenol red - Optimum activity of trypsin is achieved within the pH range of 7 to 9. The inclusion of phenol red within the specified pH range, gives the solution its pink color.
  • Diluent - Concentrated trypsin is solubilized or diluted in a buffered salt solution that contains no Ca2+ or Mg2+, such as Hank's Balanced Salt Solution, which maintains pH and osmotic balance. Some trypsin products have 0.9% NaCL as diluent instead of Hank's Balanced Salt Solution.
  • Concentration - Based on the cell type and application trypsin is used in various concentrations. For strongly adherent cell lines, trypsin of 2.5 % to 0.25% (10X to 1X power) is used. For studies requiring the integrity of cell surface proteins, lower concentrated (0.05% trypsin) solutions are employed.
