Benzonase®endonuclease efficiently removes nucleic acid contaminants from viral production, crucial for cell and gene therapies and vaccines.
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.

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
1 answer-
A concentration of 1-2 mM of magnesium is required for the activity of this product. An EDTA concentration of 1 mM partially inhibits the activity of this product.

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.
