One unit is defined as the amount of RNase A at a first-order reaction rate constant of 1.0 for catalytic hydrolysis of RNA at 25℃, pH 5.0.
Stored at -20℃ for 3 years. The enzyme is also extremely stable at room temperature.
- The enzyme is insensitive to temperature, but the optimal reaction temperature is 37 C.
- The enzyme can be active under conditions containing SDS.
- Usually the proportion of the enzyme to add to remove RNA contamination in genomic DNA is 1:200-1000.
- No further heat treatment is required before use.
