UCF.METM Uracil DNA Glycosylase (UDG/UNG) is a recombinant protein expressed and purified by E. coli and active at 25~37℃. This product is anti-pollution UDG enzyme with ultra low background bacteria residue. And this product catalyzes the release of free uracil from uracil-containing ssDNA or dsDNA by hydrolyzing the N-glycoside bond between uracil bases and sugar phosphate skeletons, producing AP sites that are easily broken by hydrolysis. This product can be widely used in common molecular biological systems such as PCR, qPCR, RT-qPCR and RT-LAMP.
Compared with Uracil DNA Glycosylase (UDG/UNG), this product has lower host nucleic acid residue, which is suitable for application with more stringent requirements on background bacteria, such as pathogen microorganism detection.

1. UDG enzyme is active in most PCR or RT-PCR reaction buffers, but it is recommended to test compatibility with the system used for the first time for self-used PCR or RT-PCR systems.
2. The enzyme should be stored in the ice box or ice bath when used, and should be stored at -25~-15°C immediately after use.
3. For your safety and health, please wear lab coats and disposable gloves for operation.
