Buccutite™ Rapid PE-Cy5 Tandem Antibody Labeling Kit
Production Scale Optimized for Labeling 1 mg Antibody Per Reaction
Buccutite™ Rapid PE-Cy5 Tandem Antibody Labeling Kits, designed for large-scale production, provide a streamlined approach for labeling antibodies with PE, APC, PerCP, and iFluor® tandem dyes. Compared to conventional protein-protein conjugation methods like the SMCC crosslinking technique, Buccutite™ conjugation is simple and more robust. Using a two-step mixing protocol, researchers can directly conjugate PE-Cy5 to any antibody or protein in less than 2 hours. Each Buccutite™ kit includes all the essential components for two labeling reactions and features a user-friendly, pre-packed spin column for maximum conjugate yield. Each Buccutite™ FOL-Activated PE-Cy5 vial provided in this kit is precisely formulated to label 1 mg of purified protein or antibody. Before labeling, it's important to remove stabilizing proteins like BSA from the sample and avoid using amine-rich buffers like Tris, which might disrupt the labeling process. Phycoerythrin-cyanine 5 (PE-Cy5) is an intensely bright, red fluorescent tandem fluorophore with an excitation and emission maxima of ~565 nm and ~666 nm, respectively. Given its intense brightness, PE-Cy5 is recommended for pairing with low-abundance targets to minimize spillover and compensation. PE-Cy5 conjugates are well-suited for flow cytometry, spectral flow cytometry, and other immunoassays requiring high sensitivity but not photostability. With Buccuitte™ Rapid Antibody Labeling kits, researchers can directly label primary antibodies, eliminating the need for secondary antibodies and enhancing panel-building flexibility.
