Lineweaver−burk plot
Nettet1. nov. 2024 · PPR virus Neuraminidase activity in Michelis plot and Lineweaver−Burk plot. The MUNANA concentration was from 6.25 μM to 400 μM. The fluorescence was measured at 37°C and recorded every 30 min by using the SpectrMax5 with excitation at 355 nm and emission at 450nm wavelengths. NettetOn the basis of the Lineweaver−Burk plots, the Michaelis constant (K m ) and the catalytic constant (k cat ) of HNE for 4 hydrolysis were determined to be 20.45 ± 1.85 μM and 21.84 ± 4.37 min ...
