Proteinase K, a potent serine protease, stands as a critical reagent in numerous biochemical and molecular biology applications. Its unique enzymatic properties, including broad substrate specificity and stability under denaturing conditions, make it invaluable for tasks ranging from nucleic acid isolation to protein digestion. NINGBO INNO PHARMCHEM CO.,LTD. provides a high-purity, reliable source of this essential enzyme, empowering researchers with exceptional tools for scientific discovery.

Biochemically, Proteinase K belongs to the peptidase family S8. It is characterized by its ability to cleave peptide bonds, with a preference for sites following hydrophobic amino acids. This non-specific cleavage pattern allows it to efficiently degrade a wide spectrum of proteins. A key aspect of its utility is its remarkable stability and activity in the presence of denaturing agents such as SDS and urea, which are commonly used in cell lysis protocols. This means that even under conditions designed to unfold proteins for easier lysis, Proteinase K can effectively degrade them, ensuring comprehensive removal of protein contaminants.

The inactivation of nucleases, particularly DNases and RNases, is another hallmark application of Proteinase K. These endogenous enzymes can degrade DNA and RNA during purification processes, compromising sample integrity. By adding Proteinase K, researchers effectively neutralize these detrimental enzymes, safeguarding their valuable genetic material. This function is critical for obtaining pure, intact DNA and RNA for downstream applications like PCR, cloning, and sequencing. The emphasis on high purity Proteinase K CAS 39450-01-6 highlights its importance in preventing contamination during these sensitive procedures.

The enzyme's activity is also influenced by certain conditions. While not dependent on calcium ions for activity, these ions can increase its stability. Conversely, it is not inhibited by EDTA, a chelating agent that incapacitates many magnesium-dependent enzymes, including some nucleases. This distinct characteristic further solidifies Proteinase K's role in protecting nucleic acids. For laboratories that need to buy Proteinase K powder for molecular biology, the flexibility of the powder form allows for precise preparation of solutions tailored to specific experimental requirements, ensuring optimal enzymatic activity.

NINGBO INNO PHARMCHEM CO.,LTD. offers medical grade Proteinase K powder, meeting the high standards required for critical research and potential diagnostic applications. The commitment to producing a reagent that is both pure and effective underscores its role as a trusted supplier in the scientific community. Whether the goal is to isolate high-quality DNA or to perform thorough protein digestion, Proteinase K is an indispensable enzyme.

In summary, the biochemical versatility of Proteinase K makes it a cornerstone enzyme in life science research. Its protein-digesting capabilities, nuclease inactivation, and robustness in various chemical environments ensure its continued importance.
