T4 Endonuclease V, also known as T4 PDG (Pyrimidine Dimer Glycosylase), is a bifunctional DNA glycosylase that combines the activities of DNA N-glycosylase and AP lyase. This enzyme is capable of recognizing and binding to cis-syn cyclobutane pyrimidine dimers, which are induced by ultraviolet radiation. It then cleaves the glycosidic bond at the 5' end of the pyrimidine dimers, releasing them and leaving an AP site. Subsequently, it utilizes its endonuclease activity to cleave the phosphodiester bond at the AP site, creating a one-nucleotide gap in the DNA strand. Applications DNA damage studies Single cell gel electrophoresis (comet assay) Specifications Source T4 Phage Molecular Weight 16.1 KD Concentration 1 U/μL Unit Definition One unit is defined as the amount of enzyme that catalyzes the conversion of 0.5 µg of UV irradiated supercoiled pUC19 DNA to > 95% nicked plasmid in a total reaction volume of 20 µL in 30 minutes at 37°C. Nicking is assessed by agarose gel electrophoresis. Irradiated plasmid contains an average of 3-5 pyrimidine dimers Components Components No. Name 14542ES76 14542ES80 14542-A T4 Endonuclease V(T4 PDG)(1 U/μL) 500 μL 1 mL 14542-B 10 x T4 Endonuclease V(T4 PDG) Buffer 1 mL 2 mL Shipping and Storage This product should be stored at-25~-15℃ for 1 years.
