Coppersensor 1 (CS1) is a boron dipyrromethene-based fluorescent sensor for selective and sensitive detection of copper(I) ions (Cu + ) in biological samples. Coppersensor 1 can be imaged using any type of fluorescence microscope, including epifluorescence, confocal and multiphoton.

Asante potassium green-1 AM is a membrane-permeable, acetoxymethyl (AM) ester-form fluorescent potassium indicator that emits in the yellow-green spectrum.Asante potassium green-1 AM is specifically tailored to measure dynamic changes in potassium ion concentrations in intracellular and extracellular environments characterized by high potassium concentrations, as it possesses a lower potassium binding affinity compared to other indicators like IPG-2 and IPG-4.

Fast Sulphon Black F serves as a specific copper indicator and is applicable for EDTA titration [1].

Sodium 2,2',2'',2'''-((((1,1-dioxido-3H-benzo[c][1,2]oxathiole-3,3-diyl)bis(6-hydroxy-5-isopropyl-2-methyl-3,1-phenylene))bis(methylene))bis(azanetriyl))tetraacetate is a useful organic compound for research related to life sciences. The catalog number is T65315 and the CAS number is 1945-77-3.

Sel-green is a selective selenol fluorescent probe used for quantifying the selenocysteine (Sec) content in the selenoenzyme thioredoxin reductase, as well as imaging endogenous Sec in live HepG2 cells.

Diantipyrylmethane is a chromogenic agent frequently utilized in spectrophotometry and extraction photometry to determine metals like Au(III), Ti(IV), Ir, Fe(III), Mo, Nd, U(IV), Ir, Pt, and Re. It is a type of biological material or organic compound extensively employed in life science research.

Ctrl-CF4-S2 is a control probe for the chemically modified Copper Fluor-4 (CF4), in which two of the four thioether ligands of the CF4 probe are replaced with methylene groups. Unlike CF4, which is a fluorescent probe used to detect the presence and distribution of copper ions, Ctrl-CF4-S2 does not respond to copper ions. This lack of response helps eliminate background signals from copper ions, thereby confirming whether the signals from CF4 accurately reflect the dynamic changes of copper ions within biological systems.

CD649.2 is a responsive fluorescent probe specifically designed for Cu(II) detection, exhibiting selectivity for metals and oxidation states. It allows for the monitoring of intracellular active Cu(II) levels via live-cell confocal microscopy. This probe provides fundamental insights into the existence and regulation of active Cu(II) levels, such as identifying divalent metal transporter 1 (DMT1) as an importer of Cu(II), observing the increase of active Cu(II) under oxidative stress induced by glutathione depletion, and examining the interaction between increased active Cu(II) and decreased active Cu(I) caused by cancerous mutations that promote oxidative stress.

C.I. 15670 is a pigment in the form of a reddish purple powder. It can be used in inks, dye lasers, vinyl polymer manufacturing, determination of iron, calcium, aluminum and tantalum in textiles, monitoring of hardness in industrial water, measurement of chlorine dioxide in drinking water, hypoglycemic agents, and nuclear fluorescent dyes.

CAY10731 is a fluorescent probe for hydrogen sulfide (H2S).[1] Upon reaction with H2S, fluorescein (FITC) is released and its fluorescence can be used to detect H2S. FITC displays excitation/emission maxima of 485/535 nm, respectively. CAY10731 is selective for H2S over glutathione (GSH), cysteine, H2O3-, SO3-, and H2O2 as well as tBuO and OH radicals. It has been used to detect H2S in rat hippocampal slices and nematodes.
