Proteinase K is a highly efficient serine protease that exhibits broad substrate specificity. It is commonly used for the digestion of proteins, including those resistant to other proteases, and is especially effective in removing nucleases from DNA and RNA preparations. This enzyme works over a wide range of temperatures and pH levels, making it versatile for various molecular biology applications. Proteinase K is a robust enzyme that can degrade a wide variety of proteins, including native proteins, during nucleic acid purification processes. It is active in the presence of SDS, urea, and other detergents, allowing it to function in complex lysis buffers. NexGen Proteinase K is available in both liquid and lyophilized forms, ensuring compatibility with different experimental needs.
