SPY555-BG can be used for widefield, confocal, SIM or STED imaging in living or fixed cells and tissue.

CoDi3 is a covalent dimerization inducer. CoDi3 can specifically, covalently and irreversibly induce the dimerization of two proteins that have been fused with O6-alkylguanine-DNA alkyltransferase (AGT, also known as SNAP-tag) in living cells. CoDi3 can act as a "sensor" for protein-protein interactions.

ONOO-LysopH is a new Rhodamine-based near-infrared fluorescent probe. ONOO-LysopH is acid-sensitive, exhibiting rapid near-infrared fluorescence enhancement around 686 nm under acidic pH conditions. ONOO-LysopH also displays a rapid NIR turn-on fluorescence around 678 nm for ONOO− at physiological pH. ONOO-LysopH can target lysosomes to track lysosomal pH changes and image endogenous/exogenous ONOO− in live cells. ONOO-LysopH is applicable for cell imaging ONOO− and tracking lysosomal pH changes.

M-H2S is an endoplasmic reticulum-targeted ratio-type near-infrared fluorescent probe (Ex/Em : 480 nm/560 nm) specifically designed for the detection of hydrogen sulfide (H2S) in living cells and zebrafish. M-H2S exhibits detection limit for H2S of 39.1 nM, and the fluorescence intensity ratio (F₆₅₀/F₅₆₀) within the range of 0-40 μM shows a linear relationship with the H2S concentration. M-H2S responds best under pH = 7.2 (the normal physiological pH of the endoplasmic reticulum) conditions, making it suitable for the detection of the microenvironment of the endoplasmic reticulum. M-H2S can be used to study the role of H2S in endoplasmic reticulum function, stress response, and related diseases.
