PAN-Biotech Trypsin Inhibitor III: 1 mg/ml in PBS, free of animal & human components (5 ml). DESCRIPTION: PAN-Biotech Trypsin Inhibitor III is a sterile solution of purified proteins to inhibit trypsin proteolytic activity. It contains no animal or human components. Supplied as 1 mg/ml in PBS solution. Trypsin Inhibitor III solution contains natural protease inhibitor proteins. APPLICATION: 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 cell detachment. Trypsin Inhibitor III is cell culture tested and is appropriate for use in cell culture applications. LIQUID/POWDER: Liquid. STERILE: Yes. STORAGE TEMP: -20°C. MANUFACTURER: PAN-Biotech GmbH (Germany).
