Animal-free, recombinant porcine Trypsin

What is TrypsiNNex®?

TrypsiNNex® is an animal-free, recombinant porcine trypsin that delivers exceptional performance and consistency for highly regulated biopharma manufacturing processes.

Trypsin is a highly specific protease widely used in biopharmaceutical production, ranging from cell dissociation, virus production, to modification of proteins and virus particles.

Advantages of choosing TrypsiNNex®

TrypsiNNex® offers the following benefits:

Eliminate the risk of viral contamination from raw material

High purity
Achieve high process consistency owing to consistently high β-trypsin content

High quality
Easy qualification or transition from your existing trypsin product, supported by extensive documentation and support from a preferred pharma grade supplier

The animal-free, recombinant TrypsiNNex® sequence is identical to porcine Trypsin and can be used as a direct replacement when converting to animal-free manufacturing. TrypsiNNex® is expressed in E. coli as an inactive product. The trypsin remains inactivated during both the upstream and downstream manufacturing process, minimizing the level of auto degradation before final stabilization and packaging, thereby preserving a high content of β-trypsin.

Trypsin has intrinsic autolytic activity and is degraded in steps, where β-trypsin is converted into α-trypsin through proteolytic cleavage (red scissors).

This process continues until the trypsin is inactivated. Intermediate forms such as Ψ-trypsin display unspecific activity, which is undesirable. Thus, a high β-trypsin content is a quality indicator that ensures consistent activity and high specificity.

TrypsiNNex® has a measured β-trypsin of typically well above the minimum specifications at 70% ensuring a high activity and consistent proteolytic pattern, which is critical when processing precursor proteins, such as pro-insulin.


TrypsiNNex® is GMP manufactured in accordance with IPEC’s guideline “The Joint Good Manufacturing Practices Guide for Pharmaceutical excipients” (2017) and applicable chapters in pharmacopoeias and ICH guidelines.

Other practical information

TrypsiNNex® is shipped on dry ice.

TrypsiNNex® should be stored at ­‑20°C ±5ºC immediately upon arrival.

Please contact us for information on storage and handling after dilution.

  • If trypsin inhibitors are needed, we can recommend using:

    • Serum (beta 2 macroglobulin) 
    • Soybean Trypsin Inhibitor

In Biopharmaceutical production, detection of raw material is necessary: 

  • Incoming testing of TrypsiNNex® (e.g. identity, activity) 
  • Detection of residual raw material in the finished product (LOQ for HPLC-based purity measurement) 


For support on incoming quality testing, please contact us. 

Although there are no specific regulatory guidelines at this time to specify allowable amounts of residual Trypsin or Collagenase, these are still considered process residuals and potential product contaminants, and thus should be assessed as part of an overall risk mitigation strategy.
