Dox-btn2 

Dox-btn2 is a biotinylated derivative of Doxorubicin (HY-15142A), with a biotin label at the point of conjugation to doxorubicin at 3'-NH₂. Dox-btn2 can be used for cell imaging. While Doxorubicin is mainly accumulated in the nucleus, while Dox-btn2 is mainly located in the cytoplasm^[1].

Dox-btn2 (1 μM; 6 h; Exc=531/40 nm and Emi=593/40 nm) exhibits visualization in U2OS cells, helps in situ mapping with Chem-map of small-molecule interactions with DNA and chromatin proteins^[1].
