Compositions and methods of using a synthetic DNAse I

摘要

Compositions and methods for making and using a synthetic bovine DNase T are disclosed. More particularly, the sbDNaseI of the present invention is a versatile enzyme that cleaves DNA nonspecifically to release 5'-phosphorylated nucleotides. The sbDNase I molecules of the present invention find particular use in a wide range of molecular biology applications, including: degradation of contaminating DNA after RNA isolation; RNA clcan-up prior to, or in conjunction with, RT-PCR after in vitro transcription; identification of protein binding sequences on DNA (DNase I footprinting); prevention of clumping when handling culture cells; tissue dissociation creation of fragmented DNA for in vitro recombination reactions.
