BP Fluor 594 NHS ester

BP Fluor 594 NHS ester is a widely used tool for modifying proteins or antibodies through the labeling of primary amines (Lys), amine-modified oligonucleotides, and other amine-containing biomolecules. The labeling process is optimal at pH 7-9, forming stable covalent amide bonds. BP Fluor 594 dye supports high molar ratio protein labeling with negligible self-quenching, resulting in brighter conjugates and more sensitive detection. BP Fluor 594 is a bright, water-soluble, pH-insensitive red fluorescent dye effective across a pH range of 4 to 10, with absorption and emission peaks at 590 and 617 nm, respectively. It is compatible with 561 nm and 594 nm laser lines. BP Fluor 594 can bind to various antibodies, peptides, proteins, tracers, and amplification substrates, and it is commonly used to generate stable signals in imaging and flow cytometry.
