The successful isolation of high-quality DNA is a foundational step in countless molecular biology research and diagnostic procedures. Among the arsenal of reagents used for this critical task, Proteinase K stands out for its potent enzymatic activity and versatility. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated molecular biology enzyme manufacturer, is proud to offer superior Proteinase K (CAS 39450-01-6) that consistently meets the high standards required for effective DNA isolation.

Proteinase K's primary function in DNA isolation protocols revolves around its ability to degrade proteins within cells and tissues. This enzymatic action is crucial for several reasons. Firstly, it helps to break down the cellular and nuclear membranes, facilitating the release of DNA. Secondly, and perhaps most importantly, it inactivates endogenous nucleases—enzymes that are capable of degrading DNA. By neutralizing these nucleases, Proteinase K ensures that the isolated DNA remains intact and free from enzymatic damage. This makes it an indispensable enzyme for DNA extraction, a process that often involves vigorous lysis and purification steps.

The effectiveness of Proteinase K is further enhanced by its stability and its response to various chemical agents. It remains active across a wide pH range and at elevated temperatures, allowing for flexibility in experimental design. Moreover, its activity is stimulated by denaturants like SDS, a common component in lysis buffers. This robustness makes our high purity proteinase K powder a reliable choice for various DNA isolation methods, whether from bacterial cells, mammalian tissues, or plant material. As a leading CAS 39450-01-6 proteinase K supplier, we ensure our product’s quality supports the most sensitive downstream applications.

When researchers worldwide look for a dependable enzyme for DNA extraction, they seek consistency, purity, and efficacy. NINGBO INNO PHARMCHEM CO.,LTD. delivers on all these fronts. Our commitment to quality as a molecular biology enzyme manufacturer means that every batch of Proteinase K is produced under strict controls, ensuring optimal performance in DNA isolation. By providing a reliable source for this essential enzyme, we empower scientists to achieve cleaner DNA preparations, leading to more accurate and reproducible results in their critical research.
