ColorWheel^® Antibody-Ready Allophycocyanin (APC) 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.

Allophycocyanin (APC) belongs to a family of phycobiliproteins and is well studied as a fluorescent reagent for flow cytometric analysis. It is isolated from a Spirulina species, a type of blue-green alga and is composed of α and β subunits. The heterodimers of these subunits can assemble as trimer or hexamer. APC displays high absorptivity and quantum efficiency. It has an excitation max at 651 nm and a emission max at 660 nm with extinction coefficient of 700,000 cm^-1 M^-1. It can absorb and emit light with low energy losses to quenching. APC can be easily conjugated to monoclonal and polyclonal antibodies for use in fluorescence-based detection methods, such as flow cytometry and FACS analysis. (Ref.: Sonani, RR., et al. (2015).
