DESCRIPTION: Fabulously Active (FabActTM) Proteinase K is a highly reactive serine protease that displays the ability to digest native proteins, thereby inactivating enzymes such as DNase and RNase without recourse to a denaturation process. It is the most powerful proteinase among all proteinases characterized so far. It cleaves at the peptide bond adjacent to the carboxylic acid group of aliphatic, aromatic or hydrophobic amino acids. The application of the molecular grade FabActTM Proteinase K is similar to the Native Proteinase K and is used in the isolation or preparation of high molecular weight nucleic acids. However, FabActTM Proteinase K is highly pure and has a higher specific activity and is more stable at room temperature as compared to native Proteinase K. It is stable and active over a wide pH range of 4-12. It can be used on any situation to digest native and denatured proteins. FabActTM Proteinase K is also active with SDS, urea and EDTA and the most active temperature is 65°C.



Figure 1: Calculated Activity at 37°C, pH 8.0: Native Prot K: 802 nmol/min/mg (802 U/mg) or 16 kU/mL for 20 mg/mL solution; Molecular Grade Prot K: 1072 nmol/min/mg (1.07 kU/mg) or 21 kU/mL for 20 mg/mL solution. *One unit is defined as the amount of protease that cleaves the FITC-labeled casein substrate to yield an amount of fluorescence equivalent to 1.0 nmol of unquenched FITC per minute at 37°C, pH 8.0.
