Cyanide Probes

CyanideOrange v4

Our water, MeOH, EtOH soluble fluorescent Cyanide probes readily chelate cyanide with relatively high binding constants (µM). We offer probes which can be used in a fluorescence intensity, excitation wavelength ratiometric (colorimetric - simple color change) or fluorescence emission wavelength ratiometric manner. We offer both “Turn On” (brighter in response to Cyanide) as well as "Turn Off" (incrementally less fluorescent in the presence of increasing cyanide) cyanide molecular fluorescent sensors. Our large range of cyanide probes are ideal for customers measuring free cyanide typically in the range 1–2 mM, with many of our probes showing dramatic responses to cyanide in the 1-200 µM concentration range.  Our "Turn-On" Cyanide Red™ fluorescent sensor is our longest wavelength emission cyanide sensor, ~650 nm, with an excitation wavelength ~440 nm.

Our cyanide probes are sold dry and are simply reconstituted by adding water/MeOH/EtOH and/or buffer. One vial of our cyanide probe will typically allow for 10 cyanide measurements to be undertaken, when further diluted into 3 cm3 volumes within a cuvette.

Ursa BioScience™ also offers quick convenient cyanide sensing kits, with a selection of cyanide probes already dispensed within plastic 1-1-4 cm cuvettes for easy, quick and no hassle use. Our Broad Wavelength Cyanide Sensing Kit™ (BWCS Kit) contains 5 cyanide probes dispensed individually within 1-1-4 cm cuvettes, for customers wishing to try the significant advantages of our dyes over a broad wavelength range. The BWCS kit contains 100 cuvettes, 20 cuvettes each of Cyanide Violet™, Cyanide Blue™, Cyanide 2™, Cyanide 3™ and Cyanide Orange™.

For optimum performance, probe vials should be stored at -2 to -8 C when not being used. Probe solutions should be used after dilution.
