UltraNuclease (EC 


UltraNuclease (EC is a non-specific endonuclease that cleaves both DNA and RNA. It is produced by the bacterium Serratia marcescens. UltraNuclease is a highly active enzyme, with a turnover number of up to 100,000 units/mg. It is also very stable, and can withstand high temperatures and pH extremes.

UltraNuclease is widely used in molecular biology and biotechnology for various applications, including the removal of contaminating DNA and RNA, manipulation of nucleic acid samples, and preparation of samples for molecular analyses. It can also be utilized in diagnostic and research applications, as well as in DNA and RNA purification processes.

This enzyme is commonly employed in research laboratories and the industry to facilitate the handling of DNA and RNA, thereby enabling a better understanding of biological and molecular processes. It is appreciated for its specificity and effectiveness in targeted degradation of nucleic acids.

DNA FragmentationTo fragment DNA for various molecular biology techniquesUltraNuclease, DNA sample, reaction buffer, EDTACombine DNA sample, UltraNuclease, and reaction buffer in a sterile tube. Incubate at 37°C for 30 minutes. Stop the reaction by adding EDTA. Analyze the fragmented DNA using agarose gel electrophoresis.
Site-Directed MutagenesisTo introduce mutations into DNAUltraNuclease, DNA template, oligonucleotide primers, reaction buffer, DpnI restriction enzymePerform PCR using the DNA template and oligonucleotide primers to amplify the desired region. Treat the PCR product with DpnI restriction enzyme to digest the parental template DNA. Combine PCR product, UltraNuclease, and reaction buffer in a sterile tube. Incubate at 37°C for 30 minutes. Transform the reaction product into competent cells using a suitable transformation method. Screen the transformants for the desired mutation using a suitable method.
Drug ScreeningTo screen for drugs that bind to specific DNA or RNA sequencesUltraNuclease, drug candidates, DNA or RNA sample, reaction bufferCombine DNA or RNA sample, UltraNuclease, drug candidate, and reaction buffer in a sterile tube. Incubate at 37°C for 30 minutes. Analyze the DNA or RNA sample using agarose gel electrophoresis to see if it has been cleaved by UltraNuclease.

Here are some specific examples of how UltraNuclease is used in biotechnology:

  • DNA fragmentation: UltraNuclease can be used to fragment DNA for Southern blotting, northern blotting, and other molecular biology techniques.
  • RNA fragmentation: UltraNuclease can be used to fragment RNA for RNA sequencing and other transcriptome analysis techniques.
  • Site-directed mutagenesis: UltraNuclease can be used to create double-stranded breaks in DNA at specific locations. These breaks can then be repaired by the cell to introduce mutations at the desired sites.
  • Drug screening: UltraNuclease can be used to screen for drugs that bind to specific DNA or RNA sequences. This is done by incubating UltraNuclease with a mixture of drugs and DNA or RNA. If a drug binds to the DNA or RNA, it will protect it from cleavage by UltraNuclease.
  • Protein purification: UltraNuclease can be used to remove nucleic acids from proteins. This is done by incubating UltraNuclease with a mixture of proteins and nucleic acids. The UltraNuclease will cleave the nucleic acids, but it will not cleave the proteins.

UltraNuclease is a valuable tool for a variety of biotechnology applications. It is a highly active, stable, and versatile enzyme.
