Cat. No.: DN1-1k (for 1KU)
Cat. No.: DN1-10k (for 10KU)
Components
Unit Definition
Using calf thymus DNA as substrate, under the condition of 25°C and pH 5.0, the enzyme amount needed to increase the 260 nm absorbance of the reaction solution by 0.001 in 1 minute is defined as one active unit (Kunitz unit).
Storage
Minimum shelf life is 2 years under -20°C.
Inactivation
Generally, DNase I can be inactivated by heating. If it is necessary to remove the residual denatured protein, the RNA sample can be extracted and precipitated with phenol chloroform after digestion at 37°C (without heating).
