About this item
Proteinase K is a highly active 28,904-Da serine protease isolated from the fungus Tritirachium album
The enzyme inhibits broad cleavage specificity on native and denatured proteins. It is widely used in the purification of DNA and RNA. Its activity is increased in the presence of denaturants such as SDS (1%) and elevated temperatures (50 to 60 °C). The recommended working concentration is 50-100 µg/mL for tissue treatment.
