In the fast-paced world of molecular biology, the purity of your DNA and RNA samples is paramount. Contaminating proteins and nucleases can wreak havoc on your experiments, leading to compromised results or complete failure. This is where a high-quality enzyme like Proteinase K becomes an indispensable tool. As a leading Proteinase K supplier in China, we are dedicated to providing researchers with the reliable reagents they need to succeed.

Proteinase K is a robust serine protease, renowned for its broad substrate specificity. Unlike many other proteases, it remains highly active in the presence of common laboratory detergents such as SDS (sodium dodecyl sulfate) and denaturing agents like urea. Furthermore, it is remarkably stable and active across a wide pH range, typically from 4 to 12.5, with an optimum around pH 8.0. This resilience makes it exceptionally well-suited for its primary application: the digestion of proteins during DNA and RNA isolation procedures.

The key benefit of incorporating Proteinase K into your workflow is its ability to efficiently degrade a vast array of proteins, including endogenous nucleases (DNases and RNases) that are notorious for degrading nucleic acids. By adding Proteinase K to your lysis buffer, you effectively neutralize these enzymatic threats, safeguarding your DNA and RNA from degradation right from the start. This is crucial for obtaining intact, high-molecular-weight nucleic acids, which are vital for downstream applications like PCR, sequencing, and gene cloning.

When you buy Proteinase K online from a reputable manufacturer, you are investing in the integrity of your research. Our Proteinase K is rigorously tested to ensure it is free from detectable levels of DNase, RNase, and nickase activity. This guarantees that the enzyme itself will not interfere with your nucleic acid preparations. We offer various grades and pack sizes to meet diverse laboratory needs, whether you are performing routine extractions or specialized genomic research.

For researchers looking to purchase Proteinase K, understanding the specifications is key. Our product typically exhibits an activity of ≥ 30 units/mg (on a dried basis), and its appearance is a clean white to off-white powder. The standard molecular formula is C29H27N2O12P, and the CAS number is 39450-01-6. When sourcing from a reliable Proteinase K manufacturer, you can be confident in the consistency and quality of the enzyme, batch after batch. This consistent performance is critical for reproducible scientific outcomes.

In summary, if you are seeking to enhance the efficiency and success rate of your DNA and RNA isolation protocols, look no further. Our high-purity Proteinase K is the enzyme you need. We provide a dependable supply, competitive pricing, and excellent customer support. Contact us today to discuss your requirements or to place an order for this essential molecular biology reagent.
