(DB-411403)
AF 700 Carboxylic Acid is a near-infrared (NIR) fluorescent dye that is structurally identical to Alexa Fluor 700. With its high photostability and pH resistance, it has become one of the most widely used fluorophores in life sciences.
Its excellent photostability and low background fluorescence make it well suited for multicolor flow cytometry and other fluorescence-based applications. AF 700 is excited by standard 702-723 nm red lasers and enables sensitive detection while preserving visible-spectrum channels for multiplex experiments.
AF 700 Carboxylic Acid is a non-reactive dye used as a reference standard or for labeling peptides and proteins. Its carboxyl group can be activated (e.g., sulfo-NHS, TFP) or modified via carbodiimide chemistry for conjugation to amino groups. It’s commonly used in solid-phase peptide synthesis with activators like HATU.
