AF488 carboxylic acid

AF488 is a bright green-fluorescent dye that is commonly used in microscopy and cell assays because of its photostability. AF488 can be used with DAPI and is well suited to multiplex assay. This high quantum yield dye has fluorescence stability within the pH range from 4 to 10.,AF488 carboxylic acid is a non-reactive AF488 form that can be used as a reference standard in experiments where AF488 conjugates are used. The carboxylic acid can be also used for the synthesis of activated esters [such as sulfo-NHS, TFP (2,3,5,6-tetrafluorophenol) and STP (4-sulfo-2,3,5,6-tetrafluorophenol)] or modified with hydrazines, hydroxylamines, or amines in aqueous solutions using water-soluble carbodiimides. Thus, this derivative can be conjugated to molecules that contain amino groups, such as proteins, antibodies, and peptides. Therefore, AF488 carboxylic acid is used during solid-phase peptide synthesis for peptide modification in situ in the presence of activating agents such as HATU.
