Known Application
Sulfo-TAG NHS-Ester is widely used for efficient antibody labeling by specifically conjugating to primary amine groups on proteins — such as lysine residues — forming stable amide bonds ideal for antibody functionalization. Its water-soluble nature allows it to dissolve directly in physiological buffers without penetrating cell membranes, making it highly suitable for precise labeling of cell surface proteins. Additionally, Sulfo-TAG NHS-Ester significantly enhances signal-to-noise ratios in assays such as ELISA and immunohistochemistry, supporting the development of high-sensitivity diagnostic reagents.
