Proteinase K is commonly used in molecular biology and biochemistry applications to digest structural proteins and enzymes. It is useful in removing nucleases that can degrade DNA and RNA, as well as in the isolation of intact genomic DNA from various sources.
The use of Pro K in combination with other reagents, such as detergents and chaotropic agents, can help to disrupt the cell membranes and release DNA from tissue. This is particularly important for downstream applications such as PCR, sequencing, and other molecular biology techniques that require pure and intact DNA.
In blood DNA extraction, Proteinase K, an enzyme commonly used to degrade proteins, can help break down the cellular and nuclear membranes, releasing DNA from the cells that protect it from degradation and increase purity/yield making it more suitable for various molecular biology techniques.
The cost of proteinase K can vary depending on the source, purity, manufacturing process and vendor’s quality management system. It is important to balance the cost with the desired quality, performance, documentation and technical/quality support to select the optimal Proteinase K for the intended application
