General description
A 3′→5′ exonuclease which catalyzes the removal of mononucleotides from the 3′-end of dsDNA. The enzyme also has apurinic and apyrimidinic endonuclease, 3′-DNA phosphatase, and RNase H activities. Activity is strongly dependent on temperature, salt concentration, and the ratio of enzyme to DNA, therefore reaction conditions must be optimized for specific applications.
Application
Suitable for:
- Production of strand specific probes
- Preparation of single stranded templates for Sanger dideoxy sequencing
- Site directed mutagenesis
Components
Exonuclease III is supplied as a solution in 5 mM potassium phosphate (pH 6.5), 200 mM KCl, 0.05 mM EDTA, 5 mM 2-mercaptoethanol, 200 μg/ml BSA, and 50% glycerol.
Unit Definition
One unit releases 1 nmole of acid-soluble nucleotides from sonicated calf thymus DNA in 30 min at 37 °C.

An amplified multiplexed DNA detection biosensor has been developed, which combines the unique cleavage function of exonuclease III (Exo III) with the separating ability of magnetic microparticles (MMPs). By using different fluorophores, the multiplexed detection of DNA is demonstrated.

We report here a graphene oxide (GO)-based fluorescent aptasensor for adenosine detection by employing exonuclease III (Exo III) as a signal amplifying element. In the absence of adenosine, the adenosine aptamers hybridized with the complementary DNA (cDNA), and the Exo

The network consisting of three kinds of unlabeled stem-loop DNA molecular beacons (MBs) is activated by target DNA in the presence of exonuclease-III (Exo-III), achieving the concept of exonuclease-assisted cascaded recycling amplification (Exo-CRA) for DNA detection with a wide dynamic

Based on the specific folic acid-folate receptor (FA-FR) interaction, macromolecular FR can bind with FA-linked DNA-small molecule chimeras, which can prevent enzymolysis by exonuclease III (Exo III), enabling a novel fluorescence biosensor for FR to be developed using quinaldine red
