UDG (uracil DNA glycosylase) can catalyze the hydrolysis of the N-glycosidic link between the uracil base and the sugar-phosphate backbone in ssDNA and dsDNA. It can easily control aerosol pollution and is suitable for common molecular biology systems such as PCR, qPCR, RT-qPCR and LAMP.
10 U of this product was detected by E.coli 16S rDNA-specific TaqMan qPCR, and the result showed that E.coli genome residue was fewer than 10 copies
No nucleic acid endonuclease, exonuclease and RNase residues
Uracil is the sole base recognized by this enzyme
Remove ssDNA and dsDNA, but they are inactive to RNA
Eliminate false positive results due to contamination of PCR amplification products.
Compatible with PCR, qPCR, RT-qPCR, etc
