Product Description
Maleimido-C3-NTA is utilized to modify the surfaces on which thiol groups are attached. Through the NTA moiety attached to the surface, genetically expressed protein, bearing a hexahistidine extension at its terminus, can be immobilized via Ni (II) (His-Tag method). Using this technique, Dr. Noji and co-workers were able to directly observe the rotation of F1-ATPase with a fluorescence microscope.
