pH value: 8.0±0.1
Volume activity: ≥1 U/μL
Unit definition: One unit Uracil-DNA Glycosylase, heat-labile, is defined as the amount of enzyme required to completely degrade 1 μg purified single-stranded uracil-containing DNA (bacteriophage M13, grown in E.coli CJ236 dut-ung-) at +37°C within 60 minutes. For comparison, one Lindahl unit is comparable to 520,000 units based on our unit definition. One Lindahl unit is defined as the amount of enzyme required to release 1 mol uracil at +37°C in 1 minute.
Unspecific endonucleases (MWM III DNA and M13mp9 ssDNA): Not detectable in up to 20 U after 16 hours incubation at +37°C.
Nicking activity (pBR322 DNA): Not detectable in up to 20 U after 16 hours incubation at +37°C.
Ribonucleases (MS2 RNA): Not detectable in up to 10 U after 4 hours incubation at +37°C.

Animal-derived additives: None
Stability: At -15 to -25°C within specification range for 18 months.", "Country": "XG", "Code": "Specification", "Name": "Specification" }, { "Language": "en", "Value": "Uracil-DNA Glycosylase hydrolyzes uracil-glycosidic bonds in DNA, creating abasic sites where the DNA is cleaved by heat, alkali, or endonuclease treatment.

CAS Number: 39369-21-7
Specificity: Hydrolyzes uracil-glycosidic bonds in single- and double-stranded DNA; no activity on dU-free natural DNA and RNA.
Incubation: +15 to +25°C for 10 minutes are recommended for treatment of PCR mixtures; at higher temperatures the enzyme stability decreases.
Half life at +40°C: About 2 minutes
Heat inactivation: +95°C for 2 minutes are sufficient for inactivation
pH optimum: 8.3-8.9
Inhibition: Activity does not depend on metal ions; no inhibition in presence of EDTA or other chelating reagents.", "Country": "XG", "Code": "Properties", "Name": "Properties" } ] } } ] }
