Product Info
Proteinase K is one of the most active endopeptidases known. The enzyme is extraordinarily effective against native proteins and can be used for quickly inactivating endogenous RNases and DNases. Proteinase K is particularly suitable for isolating nucleic acids for use in amplification reactions, for isolating native RNA and DNA from tissues and cell lines, for promoting cell lysis by activating a bacterial autolysis factor, and for modifying proteins and/or glycoproteins on cell surfaces (for membrane structure analyses).
Inhibitors: None of the following inactivate the enzyme: metal ions,
chelating agents (such as EDTA), sulfhydryl reagents, or trypsin and
chymotrypsin inhibitors.
Activators: Proteinase K activity is stimulated by the presence of
denaturing agents (SDS and urea).
Note: SDS can produce a seven-fold increase in Proteinase K activity.
Optimum pH: Proteinase K is stable over a broad pH range (4 to
12.5), and retains its full activity for several hours if incubated at a
pH between 6.5 and 9.5.
The enzyme can reduce proteins to free amino acids if a large excess
of protein is present and if incubated for long periods of time.

Specifications
Concentration:
20 mg/mL at an activity of 20 U/mg
Quality control:
Proteinase K is lyophilized and purified via chromatography, after which it is tested to ensure that no RNases, DNases and exonucleases are present. These should not be detectable.
