Blocking Powder

Blocking Powder SKU # E-IR-R108 Applications IF, FCM Product Details Product Introduction Proteinase K is a kind of high activity Proteinase of subtilisin, which is used to degrade proteins in biological samples. It can be used to digest various proteins, and it can be used in a variety of molecular biology, cell biology and other related experiments, such as genomic DNA extraction, enzyme digestion and removal, cell permeability and so on.Enzyme activity, > 30 U/mg. At 37°C, the amount of Proteinase K that can produce amino acids or polypeptides equivalent to 1 micromol of tyrosine Folin positive in one minute with hemoglobin as the substrate is defined as a unit of Proteinase K activity.The effective pH range of Proteinase K is pH4.0~12.5, and the optimal pH range is pH7.5~8.0.The optimum reaction temperature of Proteinase K is 65°C, but at 65°C or higher, Proteinase K can also degrade rapidly. It is suggested that the optimum reaction temperature is 50~55°C. Applications IF, FCM Storage Store at -20°C Valid for 12 months. Avoid freeze / thaw cycles.
