PROTEINASE K (Tritirachium album) PRK222 20mg/ml solution (>600 units/ml) DNase/RNase: not detected

Proteinase K (Molecular Biology Grade Solution) is a serine peptidase with a very high specific activity and a broad spectrum of protein digestion possibilities. The solution is designed to be used for protein degradation (up to tetrapeptides) during the cell lysis and RNA/DNA extraction procedures under hush reaction conditions such as the higher temperatures and the presence of detergents. The enzyme efficiently degrades DNases and RNases during nucleic acid isolation process. The high purity
