Proteinase K aids in molecular biology applications by digesting structural proteins, removing nucleases, and isolating intact genomic DNA.
Balancing Proteinase K cost with quality and technical support ensures optimal enzyme selection for diverse applications.
Guidelines on use of proteinase K, an enzyme commonly used to degrade proteins, and protect DNA and RNA from degradation in samples.
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.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
