Recombinant Vaccinia Virus H6R protein

Cat.No.: H6R-323
Product Overview: Recombinant Vaccinia Virus H6R was expressed in E. coli.
Description: Vaccinia virus Topoisomerase I is a type I eukaryotic topoisomerase that removes both positive and negative superhelical turns (also called right- and left-handed supercoils) from covalently closed DNA. The product of the reaction is a covalently closed, circular DNA with fewer positive or negative superhelical turns. DNA Topoisomerase I does not absolutely require Mg2+ to function, although low concentrations of Mg2+ may increase activity
Source: E. coli
Species: Vaccinia Virus
Form: Vaccinia virus Topoisomerase I: 10,000 units/ml in 10 mM Tris-HCl, 1 mM DTT, 0.1 mM EDTA, 50% glycerol, pH 7.5 @ 25 centigrade
Unit Definition: One unit of Vaccinia virus DNA Topoisomerase I will convert 1 µg of supercoiled DNA (Form I) to relaxed closed circular DNA (Form II) in 1 hour at 37 centigrade under standard assay conditions.
Applications: Studying the effects of supercoiling on transcription in vitro.Studying chromatin reconstitution in vitro.Determining the degree of supercoiling of naturally occurring DNA.Detecting mutant plasmids that differ in length by only one basepair.Increasing restriction endonuclease digestion of resistant DNA substrates by unwinding the DNA coils to expose restriction sites.
Quality Control Test: The absence of exo- and endodeoxyribonucleases, non-specific DNase and RNase is confirmed by appropriate quality test.
Storage: Store at -20 centigrade
