Általános leírás
Benzonase® nuclease is a highly efficient and genetically engineered endonuclease that originates from Serratia marcescens[1]. This dimeric protein with two essential disulfide bonds [2] is capable of attacking and degrading all forms of DNA and RNA (single-stranded, double-stranded, linear, and circular) under a wide range of operating conditions. Benzonase® nuclease is capable of removing nucleic acids and enhancing the purity and quality of protein samples.
Alkalmazás
Benzonase® Nuclease has been used: as a component in ice-cold lysis buffer C to digest DNA and RNA to facilitate the complete release of all nuclear proteins[3] in the immunoprecipitation step to release protein complexes from the nucleoplasm and chromatin[4]as a supplement in RIPA to fractionate SHSY5Y cells for immunoprecipitation[5] to remove residual nucleic acids from the aortic roots in decellularization method[6]
Used for the removal of nucleic acid from protein samples.
Biokémiai/fiziológiai hatások
Benzonase® Nuclease can completely digest nucleic acids into 5′-monophosphate terminated oligonucleotides of 3 to 5 bases in length, making it the ideal tool for removing nucleic acids from recombinant proteins and for applications that require complete digestion of nucleic acids. In addition to reducing viscosity in protein extracts and preventing cell clumping, pretreatment of protein samples with Benzonase® nuclease can significantly improve their resolution on 2D gel electrophoresis by eliminating any bound nucleic acids. This versatile enzyme can digest both native or heat-denatured DNA and RNA, with its optimum pH for enzyme activity found to be 8.0-9.2. Benzonase® nuclease is effective at removing host DNA from microbiome samples. In many cases, microbiome samples (such as saliva or skin) will have a high percentage of host DNA that interferes with downstream results. Our experts show that the reduction of host DNA lowers the cost of sequencing while increasing and improving the data. Experimental data is shown in the technical article - Benzonase® Nuclease for Microbiome Workflows
Digests native or heat-denatured DNA and RNA.

Benzonase® Nuclease for reducing host DNA in microbiome workflows and enhancing taxa identification.
This page lists nine frequently asked questions and answers about Benzonase® Nuclease.
The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.
Benzonase®endonuclease efficiently removes nucleic acid contaminants from viral production, crucial for cell and gene therapies and vaccines.
Kapcsolódó tartalom
The use of Benzonase® endonuclease can significantly reduce the levels of DNA by more than 100,000-fold while also reducing viscosity and protecting downstream equipment from DNA fouling. However, optimization strategies and DoE are critical when it comes to reducing DNA in your process. Setting up a DoE for your Benzonase® endonuclease application can help you find the optimal operation conditions that deliver the required DNA clearance from your process.

I am doing a protein purification and would like to know if magnesium chloride is required in the lysis buffer when using the Benzonase. Also, would the activity of benzonase be affected when added to a lysis buffer containing EDTA

Hi, what is the ratio of E1014 : DNA and E1014 : RNA for an efficient acid nucleic removal?
1 answer-
For efficient nucleic acid removal using Benzonase® (E1014), the recommended ratio depends on the concentration of DNA or RNA in the sample. A typical starting point is 25 U/mL of Benzonase® for reducing nucleic acid content in lysates, which corresponds to approximately 1 unit of enzyme per 37 µg of DNA under optimal conditions. For lower concentrations of DNA or RNA, as little as 9 U/mL may achieve 99% removal, but higher concentrations, e.g., 90 U/mL, ensure faster and more complete degradation. Optimal activity requires 1–2 mM magnesium ions, a pH of 8.0–9.2, and incubation at 37°C. Adjustments may be needed for sample-specific factors such as buffer composition and nucleic acid load.

Hello, I plan to do proteomic for protein. When I add RIPA buffer to isolate the protein, I need to remove the DNA and RNA inside. When should I add E1014? Together with RIPA or after it?
1 answer-
Concentrations greater than 1 mM EDTA will inhibit Benzonase activity, and RIPA buffer recipes typically contain EDTA at higher concentrations than 1 mM. Therefore, Benzonase should be used after removing EDTA from the lysed sample or consider using a different lysis solution that does not include EDTA in the formulation.
