Fluo-3FF pentapotassium is a cell-impermeant fluorescent calcium indicator. Fluo-3FF is a di-fluorinated analog of Fluo-3 with a 100-fold lower affinity than Fluo-3 for calcium (Kds=42 and 0.4 μM, respectively). For its low affinity, Fluo-3FF is used for studying compartments with high concentrations of calcium, such as endoplasmic reticulum, where high affinity dyes will be insensitive to luminal fluctuations.

HOTN is a hypochlorous acid (HClO) Fluorescent indicator. HOTN is oxidized by HClO, causing cleavage of its Py +-N + moiety and a change in hydrophobicity, which in turn triggers aggregation-induced emission to generate a strong fluorescent signal. HOTN is used for in vivo imaging of inflammation and hepatocellular carcinoma, as these diseases typically result in high levels of HClO .

Photoactive NTR probe (Compound 1) is a covalent crosslinker and Fluorescent indicator targeting Nitroreductase. The Photoactive NTR probe undergoes a sequential activation process: it is first activated via nitroreductase-mediated nitro-to-amino conversion, and then forms a fluorescent product upon photoactivation. The Photoactive NTR probe can form covalent adducts with the side chains of cysteine, tyrosine, lysine and histidine in adjacent proteins to reduce fluorophore diffusion. The Photoactive NTR probe enables super-resolution (STORM) imaging of active mitochondrial nitroreductase microdomains in living cells .
