Tocris Bioscience™ preQ1-biotin

Beskrivelse
preQ1-biotin is a modified analog of the natural substrate prequeosine1 (preQ1) and is used for RNA-TAG (transglycosylation at guanosine) and DNA-TAG. preQ1-biotin enables affinity tagging and pull-down of specific RNAs that have been modified selectively by E. coli tRNA guanine transglycosylase (TGT). preQ1-biotin is incorporated site-specifically and covalently into RNAs containing a short harpin nucleotide recognition motif. The guanine in a UGU recognition element is exchanged with the preQ1-biotin substrate.
Plasmids for expression of the E.coli TGT enzyme ( #138201 ) and for cloning an RNA of interest into a vector containing the recognition motif at the 3' end ( #138209 ) are available from Addgene.
