ColorWheel^® Antibody-Ready FITC Dye

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

Fluorescein isothiocyanate (FITC) is an amine-reactive derivative of fluorescein dye that is one of the simplest and most commonly used reagents for antibody and protein labeling applications. It is suitable for use in fluorescence microscopy, Flow Cytometry, and other immunofluorescence-based assays. Its NHS ester form reacts efficiently with primary amino groups (-NH2) in neutral to slightly alkaline (pH 7 to 9) buffers to form stable amide bonds. It displays excitation max at 494 nm and emission at 518 nm and has an extinction coefficient of 70,000 M-1 cm-1.
