DyLight® fluorochromes exhibit high fluorescence intensity, photostability and water solubility and remain fluorescent from pH 4.0 and pH 9.0. Additionally, the water solubility of the DyLight® fluorochromes allows a high dye-to-antibody ratio to be achieved without causing precipitation of conjugates.
DyLight® fluorochromes have absorption maxima ranging from 350 nm to 777 nm, covering the entire visible light spectrum. Both the absorption and emission properties of the DyLight® fluorochromes are compatible with the excitation and detection wavelengths of common fluorescence instrumentation.
Our catalog includes secondary antibodies conjugated with DyLight® 488, DyLight® 550, DyLight® 594 and DyLight® 650.
