Product Overview

Crude trypsin is often the subculturing agent of choice for cell dissociation/ disaggregation of adherent cells, although the treatment may be cytotoxic if prolonged. Over-trypsinization is a common cause of subculture problems. When using crystalline trypsin versus crude trypsin forms, crystalline trypsin does not damage cells after prolonged exposure.


  • Does not require multiple-change procedures
  • Maintains better cell viability and enhances the process of cell passaging
  • Not as cytotoxic to cells with all the negative ramifications of crude trypsin
  • Contains additives that protect the cell wall, enhancing cell viability, and it is a ready-to-use solution

The complete formulation is available.



Storage Conditions -20°C
  • Cells must NEVER remain in the crude trypsin for longer than 3-5 minutes as they may be seriously damaged in the process (i.e. damage to the intracellular proteins).
  • Cells should NEVER be left without a fluid layer.
  • The use of crystalline trypsin, rather than crude trypsin, most often performs better long-term cell growth in serum-free medium formulations. It is specifically formulated to have a gentle nature with much better cell viability, in which the cells are not subject to the vagaries of time and circumstance as when the cruder forms of trypsin are utilized.
