Advantages (Cat. # PK000011, PK000100)
- Active in detergents and reagents
- Broad pH range (4.0-12.5, optimum pH8.0)
- Active temperature range of 25°C to 65°C during use
- Lyophilized Proteinase K retains enzymatic activity at room temperature for extended periods
- Effective protein digestion and contamination removal
Protein digestion and contamination removal during nucleic acid purification to prepare RNA and high molecular weight DNA for subsequent reactions
Lyophilized Proteinase K should be stored at 2-8ºC for extended periods. Proteinase K solutions are stable for 6 months at 2-8ºC.
The quality of Proteinase K is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system.
Proteinase K Functional Test Data
|Figure 1. 0.5 cm mouse tail samples following incubation at 60ºC for 24 hours. The mouse tail on the left is the control (ddH2O) and the mouse tail on the right was digested in 20 µl of Proteinase K.|
Figure 2. Geneaid lyophilized Proteinase K is stable for at least 3 months when stored at ambient temperatures. DNA was extracted from 200 µl of whole human blood using the gSYNC™ DNA Extraction Kit. Successful DNA extraction confirms the stability of Proteinase K when stored at 4°C and room temperature.
1-3: Proteinase K stored at 4°C
4-6: Proteinase K stored at ambient temperatures for 3 months
