Web7. nov 2024 · SPAAC is one of the most common click reactions. Bertozzi et al. in 2004 developed the strain-promoted azide-alkyne cycloaddition (SPAAC) reaction, which does … WebThe SPAAC reaction would subsequently label this azide-functionalized NAD + using cyclooctyne linked to a biotin group. For simplicity, we termed this approach the SPAAC-NAD reaction. The SPAAC-NAD reaction, in theory, may be able to enrich NAD-RNAs without RNA fragmentation to preserve the complete sequence and structural information of NAD … Web30. mar 2024 · We developed an NAD-RNA capture scheme utilizing the copper-free, strain-promoted azide-alkyne cycloaddition reaction (SPAAC). We examined the specificity of CuAAC and SPAAC reactions toward NAD-RNAs and m 7 G-RNAs and found that both prefer the former, but also act on the latter. dirty mike and the gang
