6-Fluorescein isothiocyanate(6-FITC) is a derivative of fluorescein used in wide-ranging applications including flow cytometry.

The single isomer, 6-FAM, contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid.

BETA-1 is the first twisted intramolecular charge transfer (TICT)-aggregation-induced emission (AIE) integration molecule. BETA-1 emits cyan fluorescence in lipid droplets (LDs) and red fluorescence in mitochondria. BETA-1 can be used for the simultaneous and dual-color imaging of LDs and mitochondria in vivo and in vitro.

CB2-H is a dual-channel fluorescent probe for the simultaneous detection of HOCl and ONOO-. CB2-H enables the concurrent detection of HOCl and ONOO- at two independent channels without spectral cross-interference and can be applied for dual-channel fluorescence imaging of endogenously produced HOCl and ONOO- in living cells and zebrafish under different stimulants.
