title: [Variability of parameters in enzyme kinetics. 1. Intermethod oscillations].
abstract: Kinetic parameters of urease activity have been determined by five different methods, namely: Henry, Lineweaver-Burk, Hofstee, Woolf and Cornish-Eisenthal. In no instance different methods yielded the same values for the set of parameters (Km and Vmáx).
