Preparation Note Equivalent to first 40% ammonium sulfate fraction of Mandl, I., et al., J. Clin. Invest., 32, 1323 (1953). Unit Definition One collagen digestion unit liberates peptides from collagen equivalent in ninhydrin color to 1.0 μmole of leucine in 5 hr at pH 7.4 at 37 °C in the presence of calcium ions. One FALGPA hydrolysis unit hydrolyzes 1.0 μmole of furylacryloyl-Leu-Gly-Pro-Ala per min at pH 7.5 at 25 °C in the presence of calcium ions. One neutral protease unit hydrolyzes casein to produce color equivalent to 1.0 μmole tyrosine per 5 hr at pH 7.5 at 37 °C. One clostripain unit hydrolyzes 1.0 μmole of BAEE per min at pH 7.6 at 25 °C in the presence of DTT. 性质 description For general use form essentially salt-free, lyophilized powder storage temp. −20°C 安全性 Personal Protective Equipment dust mask type N95 (US), Eyeshields, Faceshields, Gloves Hazard Codes Xn Risk Statements 36/37/38-42 Safety Statements 22-24-26-36/37 WGK Germany 1
