Product Description

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.

Application example

1. Preparation of the PCR reaction mixture according to the following system

Components	Volume (μL)	Final concentration
10×PCR Buffer (Mg2+ Plus)	5	1×
25 mmol/L MgCl2	3	1.5 mmol/L
dUTP (10 mmol/L)	3	0.6 mmol/L
dCTP/dGTP/dATP/dTTP (10 mmol/L each)	1	0.2 mmol/L each
Template DNA	X	-
Primer 1 (10 μmol/L)	2	0.4 μmol/L
Primer 2 (10 μmol/L)	2	0.4 μmol/L
Taq DNA Polymerase (5 U/μL)	0.5	0.05 U/μL
Uracil DNA Glycosylase (UDG), 1 U/μL	1	1 U/50 μL
ddH2O	Up to 50	-

[Note]: According to the experimental requirements, the final concentration of dUTP can be adjusted between 0.2-0.6 mmol/L, and 0.2 mmol/L dTTP can be added selectively. 

2. Amplification procedure

Cycle step	Temperature	Time	Cycles
dU-containing template degradation	25°C	10 min	1
UDG inactivation, template Pre-denaturation	95°C	5~10 min	1
