Histochemistry, 70(1), 53-76 (1980-01-01)
The activity of dipeptidylpeptidase II (DPP II; E.C. 3.4.14.2) was investigated by biochemical and histochemical methods in rat, mouse and guinea-pig organs as well as in human enterobiopsies. Lys-Pro-MNA and Ala-Pro-MNA showed the most favorable kinetic properties (Km, Vmax) and

Clinical chemistry, 23(8), 1485-1491 (1977-08-01)
Enzyme activity can be measured in single cells or in cell suspensions by either static or flow microfluorometry when a fluorogenic substrate is used. We have used amino acid derivatives of arylamines as fluorogenic substrates for tagging cellular proteinases. The
