BDP TR carboxylic acid is a bright and photostable fluorophore for ROX/Texas red channel. It is moderately hydrophobic, has relatively long lifetime of the excited state, and significant two photon cross section.
This BDP TR carboxylic acid derivative can be used for the labeling of alcohols by Steglich esterification, or in non-conjugated form (non-activated carboxy group can be considered inert for applications that do not require conjugation).
