Invitrogen™ BODIPY™ 581/591 NHS Ester (Succinimidyl Ester)

Invitrogen™ BODIPY™ 581/591 NHS Ester (Succinimidyl Ester)

BODIPY® 581/591 dye is bright, red fluorescent dye with similar excitation and emission to Rhodamine Red™ and Alexa Fluor®568. It has a high extinction coefficient and fluorescence quantum yield and is relatively insensitive to solvent polarity and pH change. In contrast to the highly water soluble fluorophores Alexa Fluor® 488 dye and fluorescein (FITC), BODIPY® dyes have unique hydrophobic properties ideal for staining lipids, membranes, and other lipophilic compounds. BODIPY® 581/591 dye has a relatively long excited-state lifetime (typically 5 nanoseconds or longer), which is useful for fluorescence polarization-based assays and a large two-photon cross-section for multiphoton excitation. In addition to reactive dye formulations, we offer BODIPY® 581/591 dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection.
