6-Carboxyfluorescein NHS Ester (Single Isomer, 6-FAM-SE)
Overview
6-Carboxyfluorescein NHS ester (6-FAM-SE) is an amine-reactive fluorescent dye commonly used for high-resolution labeling of biomolecules. This product is supplied as a pure single isomer of 6-carboxyfluorescein, providing enhanced reproducibility in sensitive labeling applications. The NHS ester reacts with primary amines on biomolecules, forming stable amide bonds.
Applications
-
Precise oligonucleotide labeling for qPCR, probes, and hybridization assays
-
Antibody labeling for imaging and flow cytometry
-
Protein or peptide modification for fluorescence-based detection
Use Considerations
This single-isomer formulation ensures site-specificity and batch-to-batch consistency, making it ideal for critical assays where mixed isomers may introduce variability. NHS ester chemistry is fast and efficient under mild conditions and widely used for labeling amine-functionalized oligonucleotides and proteins.
