PAN-Biotech Trypsin Inhibitor III is a sterile solution of purified proteins to inhibit trypsin proteolytic activity. It does not contain any animal or human components.

Supplied as 1 mg/ml in PBS solution.


    Trypsin Inhibitor III solution contains natural protease inhibitor proteins. The biological activity is depending on trypsin concentration.


    For inhibiting trypsin activity in serum-free culture of adherent cells. Trypsin is used for dissociation of adhesion-dependent cells. Serum contains natural trypsin inhibitors. In serum-free cell culture the neutralizing effect of serum is absent. Therefore, it is crucial to completely block proteolytic activity from trypsin after detachment of the cells.

    Inhibits trypsin activity; Chymotrypsin and other proteolytic enzymes are inhibited to a lesser extent.

    Trypsin Inhibitor III is cell culture tested and is appropriate for use in cell culture applications.

    Application Note

    Cell exposure to trypsin solution should be as brief as possible. Overexposure to trypsin can damage cells. Cell cultures under serum-free conditions in general detach more readily and are more sensitive to trypsin. Failure to neutralize trypsin may result in a loss of the culture.
