BP Fluor 488 DBCO

BP Fluor 488 DBCO is a widely used labeling dye designed for copper-free click chemistry reactions. It reacts with azide groups present in antibodies, proteins, peptides, amino-modified oligonucleotides, and other target molecules. The dye exhibits an excitation peak at 499 nm and an emission peak at 520 nm, making it ideal for applications such as microscopy and flow cytometry. BP Fluor 488 is a pure 5-sulfonated rhodamine molecule, which minimizes batch-to-batch variation caused by isomer ratio differences.
