6-TAMRA NHS Ester (6-carboxytetramethylrhodamine, single isomer) is a high-purity amine-reactive fluorescent dye suitable for labeling biomolecules such as proteins, antibodies, and peptides. It reacts with primary amines through its NHS (N-hydroxysuccinimide) ester group, forming stable amide bonds. The single isomer form ensures consistent performance and labeling specificity.

Key Features:

• High-purity single isomer for reproducible labeling
• Strong red-orange fluorescence (excitation ~555 nm, emission ~580 nm)
• Amine-reactive NHS ester chemistry
• Ideal for labeling proteins, peptides, and antibodies

Applications:

• Protein labeling for fluorescence microscopy or flow cytometry
• Peptide labeling for biochemical assays
• Antibody conjugation for immunodetection
