General description
La nucleasa Benzonase® es una endonucleasa genotecnológica muy eficiente procedente de Serratia marcescens[1]. Este dímero proteico con dos enlaces disulfuro esenciales [2] es capaz de atacar y degradar todas las formas de ADN y ARN (monocatenarias, bicatenarias, lineales y circulares) en una amplia variedad de condiciones de funcionamiento. La nucleasa Benzonase® es capaz de eliminar los ácidos nucleicos y potenciar la pureza y la calidad de las muestras proteicas.
Application
Utilizado para eliminación de los ácidos nucleicos de las muestras proteicas.
La nucleasa Benzonase® se ha utilizado: como un componente del amortiguador C de lisis en frío para digerir el ADN y el ARN y facilitar así la liberación completa de todas las proteínas nucleares en el paso de inmunoprecipitación para liberar los complejos proteicos del nucleoplasma y la cromatina como un suplemento en RIPA para fraccionar las células SHSY5Y destinadas a inmunoprecipitación para eliminar los ácidos nucleicos residuales de las raíces aórticas en el método de descelularización
Biochem/physiol Actions
Digiere el ADN y el ARN nativos o desnaturalizados por calor.
La nucleasa Benzonase® puede digerir por completo los ácidos nucleicos en oligonucleótidos de 3 a 5 bases de longitud terminados en 5′-monofosfato, lo que la convierte en la herramienta ideal para separar los ácidos nucleicos de las proteínas recombinantes y para aplicaciones que requieran una digestión completa de los ácidos nucleicos. Además de reducir la viscosidad en los extractos de proteínas y evitar la aglutinación celular, el pretratamiento de muestras proteicas con las nucleasas Benzonase® puede mejorar significativamente su resolución en la electroforesis bidimensional en gel al eliminar cualquier ácido nucleico unido. Esta enzima versátil puede digerir el ADN y el ARN nativos o desnaturalizados por calor con su pH de actividad enzimática óptimo que oscila entre 8,0 y 9,2. La nucleasa Benzonase® elimina con eficacia el ADN huésped de las muestras de microbioma. En muchos casos, las muestras de microbioma (como la saliva o la piel) tendrán un elevado porcentaje de ADN del huésped que interfiere en los resultados posteriores. Nuestros expertos demuestran que la reducción del ADN del huésped disminuye el coste de la secuenciación al tiempo que aumenta y mejora los datos. Encontrará los datos experimentales en el artículo técnico - Benzonase® Nuclease for Microbiome Workflows
Features and Benefits
- Eliminación del ADN del huésped en muestras de microbioma.
- Digestión eficaz del ácido nucleico en una variedad de procedimientos de trabajo.
- Reducción de la viscosidad durante la extracción de proteínas.
Physical form
Disolución en glicerol al 50% que contenga Tris HCl 20 mM, pH 8,0, MgCl2 2 mM y NaCl 20 mM.
Other Notes

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.

Do you sell high salt lysis buffers that are compatible with benzonase? Do you have any written protocols for use of benzonase with high salt buffers?
1 answer-
We do not have a branded "high-salt lysis buffer" off the shelf that is compatible with benzonase. However, we offer a specialized Benzonase® Salt Tolerant Endonuclease which is active at higher salt concentration, up to1M NaCl .

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.
