UCF.ME™ UltraNuclease _ 20156ES
UltraNuclease, also known as non-specific nuclease or broad-spectrum nuclease, is a non-specific endonuclease derived from Serratia Marcescen. It can cleave at any nucleotide within the chain, completely digesting nucleic acids into 5'-monophosphate oligonucleotides of 2-5 bases in length. UltraNuclease is capable of degrading various forms (double-stranded, single-stranded, linear, circular, native, or denatured) of DNA and RNA under a wide range of conditions (6 M Urea, 0.1 M Guanidine HCl, 0.4% Triton X-100, 0.1% SDS, 1 mM EDTA, 1 mM PMSF). It is widely used for removing nucleic acids from biological...

It is widely used for removing nucleic acids from biological products.

This product is genetically engineered and expressed in Escherichia coli (E. coli), with a purity ≥99%. It is used to reduce the viscosity of cell supernatants and cell lysates, improve protein purification efficiency and functionality studies, and effectively prevent the clumping of human peripheral blood mononuclear cells (PBMCs) in cell therapy and vaccine research.

It is provided as a sterile liquid enzyme stored in buffer (20 mM Tris-HCl pH 8.0, 2 mM MgCl2, 20 mM NaCl, 50% Glycerol), appearing as a clear, colorless liquid.

FAQ

Depending on the specific requirements of the experiments, the addition amount can range from 1/100 to 1/10,000.
The activity of Benzonase will decrease by 50% or more when the following substances are present: > 150 mM monovalent cations, > 100 mM phosphate, > 100 mM ammonium sulfate, > 100 mM guanidine hydrochloride, > 0.1% SDS, > 1% Triton X-100, > 1% Tween 20.
Common biological buffers, such as TBS, MOPS (pH 6-8), etc.
The use of EDTA to chelate metal ions (concentration greater than 6 mM) can reversibly inhibit the activity of Benzonase nucleases. Extreme conditions can cause irreversible inactivation, such as 100 mM NaOH treatment for 30 minutes, etc. Benzonase nucleases can be separated from the target product using an anion exchange column or gas chromatography. Due to the stability of this nucleolytic enzyme, it is recommended not to use Benzonase nucleases in applications where the exclusion of nucleases is required in the final product.
So far, we haven't had any customers do this. If it's for dealing with cell clumping, you can add it to the reaction and then remove the total nucleases by changing the solution. In industrial virus purification, column filtration can also remove the total nucleases. When you add this and then perform nucleic acid extraction, there's no guarantee that the total nucleases will be completely removed. Once there is any residue, the extracted nucleic acids will be cut and degraded. 70℃ for 30 minutes can inactivate them. It's uncertain if this will have an impact on your blood sample. According to the instructions, 1 ul of total nucleases is equivalent to being able to handle 10 to the power of 9 cells. 200 ul of whole blood doesn't know how many cells haven't undergone whole blood processing. We can't recommend it. You can conduct a gradient test to see.
