ICG amine, a tricarbocyanine dye, is a near-infrared fluorescent probe that efficiently binds to amino acid residues without the requirement of condensing agents.

ICG-carboxylic acid is a fluorescent probe in the near-infrared (NIR) range. It is derived from indocyanine green (ICG), a commonly used fluorescent dye in medical diagnostics. ICG exhibits a peak absorption at 800 nm, allowing it to efficiently absorb energy from near-infrared lasers and release heat within the dyed tissue.

Janelia Fluor 669, SE (JF669, SE), a red fluorescent dye, can be directly reacted with the available thiol-containing HaloTag ligand under mild conditions (DIEA, DMF) to afford a JF669 HaloTag ligand in a single step (Ex = 669 nm; Em = 682 nm).

NIR-H2O2 is a cell-permeable near-infrared (NIR) fluorescent turn-on sensor. It responds to H2O2 with a large turn-on NIR fluorescence signal upon excitation in the NIR region.

Cy7-YNE is a fluorescence labeling agent (Ex=700-770 nm, Em=790 nm) used for labeling antibodies, proteins, and peptides.
