BDPep FL NHS Ester is an amine-reactive green fluorescent dye designed for peptide labeling, solid-phase peptide synthesis (SPPS), and biomolecular conjugation. It features a BODIPY-derived fluorophore engineered for improved stability under acidic conditions, along with a reactive N-hydroxysuccinimide (NHS) ester group. The NHS ester reacts with primary amines to form stable covalent amide linkages, while the fluorescent core supports molecular detection and imaging. Additionally, its compatibility with suitable TFA-containing cleavage conditions makes it useful for preparing fluorescent peptides and biomolecular probes.
