photoactivatable cyclic caged morpholino oligomers
RNA ElementPhotoactivatable cyclic caged morpholino oligomers (ccMOs) are light-responsive antisense morpholino reagents engineered in a cyclic, caged format to suppress target binding until photoactivation. In the reported design, brief 405-nm illumination photocleaves the cage and restores antisense activity, enabling spatiotemporal regulation of gene expression.
