Applications

A stable and highly reactive serine protease; used for protein and nucleic acid isolation.Proteinase K is used in the purification of RNA and DNA from tissues or cell lines. It finds application in protein modification, determination of enzyme localization and inactivation of RNases/DNases during nucleic acid extraction. It is also used in mitochondria isolation and removal of endotoxins bound to cationic proteins like lysozyme and ribonuclease A. Further, it is involved in the treatment of paraffin embedded tissue sections in order to expose antigen binding sites for antibody labeling.

Notes

Minimum 400 units per ml. Protein concentration is 20 mg/ml in 10mM Tris-HCl, 1mM calcium acetate, pH 7.5 containing 50% glycerol. RNase and DNase free. One unit releases one micromole of Folin positive amino acids, measured as tyrosine, at 37°C and pH 7.5, using urea denatured hemoglobin as the substrate.Incompatible with strong oxidizing agents. Store in a cool place.
