Abstract
- Light activation is an effective way to impart spatiotemporal control over oligonucleotide probes that are widely applied for gene expression regulation and target function investigation. Among the major oligonucleotide caging strategies, cyclization with a photocleavable linker is an elegant design, which affords both atom efficiency and stability in many biological environments. Here, we introduce an improved protocol for circular oligonucleotide synthesis requiring only one round of HPLC purification. With a series of poly‐U oligonucleotide strands of different sizes and backbone modifications, the pre‐photolysis caging stability and post‐photolysis target binding affinity were studied through a denaturing gel assay and melting temperature measurements. A 14 U 2'‐OMe RNA probe was selected, with strong potential application in transcriptome in vivo analysis (TIVA) for mRNA isolation. [ABSTRACT FROM AUTHOR]
