In the complex landscape of molecular biology, having access to reliable and high-performance enzymes is crucial for scientific advancement. Proteinase K has long been a cornerstone reagent, and as a prominent manufacturer and supplier in China, we are proud to offer a product that meets the rigorous demands of modern research. If you're seeking to buy Proteinase K, understanding its capabilities and sourcing from a dependable manufacturer is key.

Proteinase K, identified by its CAS number 39450-01-6, is a potent endopeptidase that plays a vital role in numerous molecular biology workflows. Its broad substrate specificity, targeting peptide bonds adjacent to hydrophobic amino acids, makes it incredibly versatile. This enzyme is particularly valued for its ability to digest a wide array of proteins, including highly stable ones, making it an ideal choice for sample preparation where complete protein removal is necessary.

One of the most critical applications of Proteinase K is in the isolation of nucleic acids. When preparing DNA or RNA, the presence of nucleases can lead to rapid degradation, compromising experimental outcomes. Our high-purity Proteinase K, supplied as a fine white powder, effectively inactivates DNases and RNases, safeguarding your genetic material. This capability makes us a go-to supplier for laboratories focused on genomics, transcriptomics, and diagnostics.

Beyond nucleic acid isolation, Proteinase K is instrumental in other molecular biology techniques. It is frequently used in protein fingerprinting, in activating host cell nucleases for recombinant protein expression, and in the preparation of DNA for pulsed-field gel electrophoresis. Its remarkable stability in the presence of denaturants like SDS and urea, and its activity across a wide pH range (4-12.5), further solidify its position as an essential enzyme. These characteristics ensure it performs reliably even under harsh experimental conditions.

For institutions and researchers looking for a competitive Proteinase K price, our position as a leading manufacturer in China allows us to offer cost-effective solutions without compromising on quality. We ensure that every batch of our Proteinase K meets the specified activity levels (30.0-45.0 u/mg) and purity (≧90.0%), providing you with a product you can trust.

As a dedicated supplier, we are committed to supporting the scientific community by providing consistent access to this critical reagent. Whether you require small quantities for specific experiments or bulk orders for large-scale operations, we can meet your needs. We encourage you to inquire about our Proteinase K and discover how our commitment to quality and our competitive pricing can benefit your molecular biology research. Partner with a trusted manufacturer and elevate your experimental results.
