Unlike chymotrypsin, the activity of trypsin is not affected by the inhibitor tosyl ...
WebPhenol red: Optimum activity of trypsin is achieved at pH range from 7 to 9 (5466615). At this range inclusion of phenol red gives pink color. Due to environmental conditions the pH of trypsin may turn acidic, giving orange color and renders trypsin less effective. By adjusting the pH to 7.4 – 7.6 with NaOH trypsin activity could be optimized. WebSolubility: This product is soluble in 0.67 M phosphate buffer, pH 7.6 (1 mg/mL) Trypsin inhibitor from turkey egg white contains two independent binding sites, one for bovine trypsin and the other for α-chymotrypsin. At low ph (2.0) a third domain (OMTKYT3) develops and inhibits most serine proteases that prefer a neutral complex site. 13
