Difference Between Benzonase and DENARASE®
Benzonase and DENARASE® are instrumental nucleases utilized extensively in molecular biology and biopharmaceutical domains. The pivotal distinction between them emanates from their origin and the organisms they are derived from. Benzonase originates from Serratia marcescens, while DENARASE® is a recombinant endonuclease hailing from Bacillus subtilis, engineered by c-LEcta for heightened activity.
What is Benzonase:
Benzonase is a meticulously engineered endonuclease from Serratia marcescens. Characterized as a non-specific nuclease, it possesses the capability to degrade both DNA and RNA, thereby serving as an invaluable asset in reducing the viscosity of nucleic acid-laden solutions and eradicating nucleic acid contamination in protein formulations. It is a registered trademark of Merck KGaA, Darmstadt, Germany, and is revered for its effectiveness across a broad pH spectrum (6-10) and temperatures up to 65°C, albeit with a propensity to lose activity over time.
What is DENARASE®:
DENARASE®, crafted as a recombinant endonuclease in Bacillus subtilis by the German biotechnology entity c-LEcta, mirrors Benzonase in its non-specific nuclease attribute, thus capable of degrading both DNA and RNA. It is particularly favored in the biopharmaceutical realm for similar applications to Benzonase, albeit optimized for certain production protocols, especially in degrading host-cell DNA.
Similarities Between Benzonase and DENARASE®:
- Both Benzonase and DENARASE® are recognized as non-specific nucleases with the prowess to degrade both DNA and RNA.
- They are indispensable tools for managing nucleic acid contamination and curbing the viscosity of nucleic acid-containing solutions across a myriad of biotechnological and pharmaceutical endeavors.
