A highly sensitive and simplified method for the differential determination of serum ketone bodies has been developed. Serum was deproteinized with perchloric acid, and acetoacetate contained in the supernate was reacted with newly synthesized p-nitrobenzene diazonium fluoroborate at 37 degrees
N I Tarasova et al.
Biokhimiia (Moscow, Russia), 46(2), 369-375 (1981-02-01)
p-Nitrophenyldiazonium chloride was found to modify the Tyr-75 and Tyr-189 residues in aspergillopepsin A. Incubation of the protein with a 45-fold molar excess of the reagent at pH 5,2 results in the attachment of 1,8 inhibitor residues, which leads to
