Key Product Details
Description
preQ1 with alkyne handle for click chemistry
Product Description
preQ1-alkyne is a modified analog of the natural substrate prequeosine1 (preQ1). It contains alkyne handle that enables users to attach additional groups to preQ1 via Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry. It can be used to generate photoactivatable probes that can control CRISPR gene editing via the RNA-TAG method.Other RNA-TAG toolbox compounds include preQ1-biotin (Cat. No. 7804)
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.
