5-FAM SE
5-Carboxyfluorescein N-succinimidyl ester is a high-purity, single-isomer fluorescein dye designed for the covalent labeling of biomolecules through primary amines. The NHS ester reacts efficiently with lysine residues in proteins or modified oligonucleotides, forming stable amide bonds.
Key Features
- Single isomer: Ensures defined labeling with minimal heterogeneity
- Amine-reactive NHS ester: Targets primary amines under mild conditions
- Fluorescent properties: Excitation ~495 nm / Emission ~520 nm
Applications
- Antibody or protein labeling for immunofluorescence and flow cytometry
- Peptide conjugation for receptor binding or imaging studies
- Fluorescent oligonucleotide probe synthesis for hybridization assays
