Product Information
Description
E. coli Uracil-DNA Glycosylase (UDG) catalyses the release of free uracil from uracil-containing DNA. UDG efficiently hydrolyzes uracil from single-stranded or double-stranded DNA, but not from oligomers (6 or fewer bases).Product Source
An E. coli strain that carries the UDG gene from E. coli.- This product is related to the following categories:

Properties & Usage
Unit Definition
One unit is defined as the amount of enzyme required to release 60 pmol per minute of a fluorescently labeled 47 mer single-stranded DNA oligonucleotide containing a single uracil base in 30 minutes at 37°C in a total reaction volume of 50 µl in 1X UDG Buffer.Reaction Conditions
1X UDG Reaction Buffer
Incubate at 37°C
1X UDG Reaction Buffer
20 mM Tris-HCl
1 mM DTT
1 mM EDTA
(pH 8 @ 25°C)
Storage Buffer

Heat Inactivation
NoUnit Assay Conditions
1X UDG Reaction Buffer, 1 unit of uracil DNA Glycosylase, 0.2 µg 3H-uracil DNA (104-105 cpm/μg) for 30 minutes at 37°C in a total reaction volume of 50 µl.Application Features
- Treatment of 0.1 µg of uracil-containing DNA with 1 unit of UDG for 10 minutes at 37°C renders the DNA incapable of being copied by DNA polymerase. The enzyme can be 95% heat killed by incubation at 95°C for 10 minutes. Since UDG remains partially active following heat treatment at 95°C, it is recommended that uracil glycosylase inhibitor be added to prevent degradation of product DNA. Alternatively, reaction products can be immediately extracted with phenol/chloroform.

Product Notes
- UDG is active over a broad pH range with an optimum at pH 8.0, does not require divalent cation, and is inhibited by high ionic strength (> 200 mM).

FAQs
- What is the activity of UDG in the NEBuffers 1-4?
- Will UDG work in T4 DNA ligase buffer?
- What is the molecular weight of UDG?
- Is UDG a tagged protein?
- I see that UDG works optimally at 37°C. Do you have another glycosylase that works at higher temperatures?
- Does the Uracil Glycosylase inhibitor (UGI) inhibit UDG?
- Does UDG cut RNA?
- Can UDG be used to remove dU from a short 21mer oligo? Do the dU residues need to be spaced in any special way to avoid problems with cleavage?
- Are there any specific recommendations for the use of UDG on single stranded DNA? The materials on the web and data card seem to describe conditions for use with dsDNA.
- What is the difference between UDG and UNG?
- Does UDG release uracil from ss and dsDNA?
