Invitrogen BODIPY FL dye is a bright, green-fluorescent dye with similar excitation and emission to fluorescein (FITC) or Invitrogen Alexa Fluor 488 dye. 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), Invitrogen BODIPY dyes have unique hydrophobic properties ideal for staining lipids, membranes, and other lipophilic compounds.
BODIPY FL 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.
We offer BODIPY FL dye conjugated to a variety of antibodies, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection. In addition, reactive dye forms and protein labeling kits are available to allow you to generate your own protein conjugates or probes.
