E. coli UDG is a valuable tool in molecular biology research for its ability to remove uracil from DNA templates. This enzyme is widely used in various applications, including site-directed mutagenesis, PCR amplification, and sequencing. UDG can remove uracil from the template strand of a DNA duplex, enabling the introduction of specific mutations or the creation of nicked DNA for downstream applications. Additionally, UDG is used in PCR amplification to prevent the amplification of any residual uracil-containing templates, which can lead to false-positive results. UDG has also been used in sequencing applications to remove uracil from DNA templates before sequencing, improving the accuracy and reliability of the results.

Conclusion: E. coli UDG is a highly conserved enzyme that plays a crucial role in maintaining genomic integrity by removing uracil from DNA. The crystal structure of E. coli UDG has been extensively studied, revealing the conserved catalytic mechanism and the interaction of the protein with DNA. E. coli UDG is a valuable enzyme with numerous applications in molecular biology research and potential applications in the medical field, such as cancer treatment. More research is needed to fully understand the therapeutic potential of targeting UDG. Overall, E. coli UDG is a valuable enzyme with numerous applications in molecular biology research and potential applications in the medical field.


UNG psychrophilic marine bacterium Recombinant produced in E.Coli is a single, non-glycosylated polypeptide. UNG is purified by proprietary chromatographic techniques.


Escherichia Coli.

Physical Appearance

Sterile Filtered clear solution.


UNG protein solution (1U/ul) 20mM Tris-HCl (25℃, pH 8.0), 100mM KCl, 0.1mM EDTA, 1mM DTT, 0.5% NP-40, 0.5% Tween-20 and 50% glycerol.


Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Unit Definition

1 unit is defined as the amount of enzyme that releases 1 nmol of uracils from the DNA strand (containing dU) within 1 hour at 37°C in the reaction system containing 70mM TrisHCl, pH-7.5, 10mM NaCl, 1mM EDTA and 0.1mg/ml BSA reaction liquid.

Specific Activity

200,000 U/mg.


Greater than 97.0% as determined by SDS-PAGE.


Treatment of 0.1μg of uracil containing DNA with 1U UDG for 10 min. at 37 renders the DNA incapable of being copied by DNA polymerase. The enzyme can be 95% heat killed by incubation at 95 for 10 minutes. Since UDG remains partially active following heat treatment at 95, it is recommended that uracil glycosylase inhibitor be added to prevent degradation of product DNA. Alternatively, reaction products can be immediately extracted with phenol/chloroform
