What are exonucleases and their applications?

产品信息

Nuclease BAL-31 exonuclease degrades both 3′ and 5′ termini of duplex DNA without generating internal scissions. The enzyme is also a highly specific single-stranded endonuclease which cleaves at nicks, gaps and single-stranded regions of duplex DNA and RNA (1,2).

Ligation of Nuclease BAL-31 treated fragments

A) Gel electrophoresis of Lambda DNA-HaeIII digest.  
B) Lambda DNA-HaeIII digest after 2 minute incubation with one unit of Nuclease BAL-31. 
C) As in (B) followed by incubation with T4 DNA Ligase.

产品来源

Purified from the culture medium of Alteromonas espejiana BAL-31. Contains a mixture of “fast” and “slow” species of the enzyme (3).

  • 注意事项
    1. Duplex products of the exonuclease are a mixture of blunt and staggered ends. This mixture can be cloned directly, although maximal ligation efficiency requires repairing the staggered ends with a suitable DNA polymerase.
    2. If necessary, the enzyme may be diluted in reaction buffer prior to use.
    3. Activity is linear with enzyme concentration.
    4. Heat Inactivation will only work in the presence of 30mM EGTA.
