The sodium pump or Na,K-ATPase, maintains the Na+ and K+ gradients across eukaryotic cell membranes at the expense of ATP. Incubation of purified canine renal Na,K-ATPase with 4-acetamido-4'-isothiocyanatostilbene-2,2'-disulfonic acid (SITS) inhibited the ATPase activity. Both the labeling of the protein

N-terminal derivatization of peptides with the chromogenic reagent 4-acetamido-4-isothiocyanatostilbene-2,2-disulfonic acid (SITS) is demonstrated to enhance the efficiency of 266 nm ultraviolet photodissociation (UVPD). Attachment of the chromophore results in a mass shift of 454 Da and provides significant gains in the number
