Clickable APEX2 Probe

Dual RNA labeling in live cells

A phenol derivative probe engineered for APEX2 proximity labeling that balances reactivity, hydrophilicity, and lipophilicity to enable efficient and specific RNA labeling in live cells, and can be combined orthogonally with singlet oxygen labeling.
