CUSABIO | Proteinase K -適用於COVID-19核酸提取試劑盒

• • 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

• • High Purity

• • High Stability

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%.

• • High Activity

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.
