ABSTRACT:
Compositions and method for making and using a synthetic bovine DNase I are disclosed. More particularly, the sbDNase I 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 clean-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 cultured cells; tissue dissociation and creation of fragmented DNA for in vitro recombination reactions.
