RNase R

$0.00$736.45

RNase R is an E. coli exoribonuclease which exhibits 3′ to 5′ exonuclease activity, efficiently digesting nearly all linear RNA species. This enzyme does not digest circular, lariat, or double stranded RNA with short 3’ overhangs (less than seven nucleotides).

Description

Description
RNase R is an E. coli exoribonuclease which exhibits 3′ to 5′ exonuclease activity, efficiently digesting nearly all linear RNA species. This enzyme does not digest circular, lariat, or double stranded RNA with short 3’ overhangs (less than seven nucleotides). RNase R is ideally suited to the study of lariat RNA produced by traditional splicing, as well as circRNAs which arise through back-splicing. By removing linear RNAs from cellular or RNA extracts, RNase R greatly facilitates the identification of circular species through RNA-sequencing.

Applications
• Alternative splicing studies
• Gene expression studies
• Intron cDNA production
• Intronic screening of cDNA libraries
• Isolation of splicing intermediates and lariats
