**CO-1** is cell permeable background-free probe  through optimized lipophilicity, water solubility and charged van der Waals surface area. **CO-1**, a cyclooctyne-containing BODIPY probe, is also specifically label intracellular azide-tagged organelles & engineered proteins with minimum background.

Fluorescence imaging of mitochondria, lysosome and golgi apparatus in U-2 OS cells labelled with **CO-1**. Cells pre-treated with TPP-Az, Morph-Az or Sphingo-Az were incubated with 2 μM CO-1 in growth media at 37 °C for 1 h and followed by counterstaining with organelle trackers. Scale bar, 15 μm. (iv) Fluorescence imaging of histone H2B in live U-2 OS. U-2 OS cells were co-transfected with plasmids pIre-Azi3 and pmH2B-6-mKate2-16tag to incorporate UAA Azi into H2B-mKate2 at site 16. After Azi incorporation, cells were labelled with 10 μM CO-1 for 90 min at 37 °C. Cells were then washed and imaged. The mKate2 (red) signals were detected in cell nuclei only, and colocalized with the **CO-1** (green) signals in the merged image. Scale bar, 5 μm.
