Description: AFDye™ 555 Maleimide is a water-soluble, bright orange-fluorescent dye with excitation ideally suited for the 532 nm or 555 nm laser lines and visualized with TRITC (tetramethylrhodamine) filter sets. AFDye™ 555 conjugates of antibodies, peptides, and proteins are pH insensitive from pH 4 to pH 10. Proteins can be labeled with AFDye™ 555 dye at high molar ratios without significant self-quenching, leading to brighter conjugates and more sensitive detection. AF 555 conjugates ideally suited for detection of low abundance targets.
