Cruzfluor™ 488 succinimidyl ester is a superior protein conjugate fluorescein derivative for FITC and comparable replacement for Alexa Fluor® 488 NHS ester, Cy2®, DyLight® 488 and Fluorescein. Cruzfluor™ 488 succinimidyl ester dyes have selectivity for protein amino groups and a respective excitation and emission maxima of 491 nm and 520 nm, and the conjugates are more stable, magnitudes brighter and do not have some of the limitations that are found in FITC. The CruzfluorTM 488 is unaffected by pH 4-10, a marked improvement over a necessary pH above 9 for maximum fluorescence and does not suffer photobleaching for microscope imaging. Additionally, CruzFluor™ 488 (CFL 488) is offered conjugated to commonly used secondary antibodies for use in flow cytometry and immunofluorescence.
The CruzFluorTM family of products are a fluorescent labeling dye series that spans the full visible spectrum, and are useful to conjugate to nucleic acids, proteins and antibodies. The CruzFluorTM dyes are strong reagents for amine modification because they are incorporated with succinimidyl esters, which have a very strong ability to develop amide bonds that are as stable if not identical to the bonds found on a natural peptide.
