CUSABIO | Proteinase K -適用於COVID-19核酸提取試劑盒
CUSABIO Proteinase K is applied in the nucleic acid extraction kit and completely digest various nucleases and other proteins. It can prevent viral nucleic acid degradation and optimize extraction efficiency.
Complete Degradation of Nuclease
Detect Nucleic acid residue by agarose gel electrophores
Detect DNase residue by agarose gel electrophores
Detect RNase residue by agarose gel electrophores
Purity greater than 95% as determined by SDS-PAGE.
Enzymetic activities were asaayed every month during one year. It indicates that proteinase K is stable and enzyme activity is maintained more than 95%.
Using the absorbance A275 as the vertical axis and different concentrations of tyrosine as the horizontal axis, a standard curve was drawn, and the enzyme activity was calcu lated ＞30U/mg.
Activity measurements from cusabio were compared to from three other vendors. Proteinase K from cusabio is better than other vendors.
