FSD Fluor™ Antibody Labeling Kits

Fluorescent labeling is a powerful technique for studying protein localization, cellular dynamics, and molecular interactions. GeneTex’s FSD Fluor^TM Antibody Labeling Kits enable rapid covalent labeling via lysine ε-amino groups using FSD Fluor^TM NHS ester dyes.

With only 10 minutes of hands-on time and ready-to-use conjugates in about one hour, researchers can quickly generate fluorescently labeled antibodies for microscopy, cell imaging, and other fluorescence-based applications.

Designed for simplicity and reliability, FSD Fluor^TM kits make fluorescent labeling faster, easier, and more reproducible.
