Figure 8.
Isozymatic NADP-ME activity in green sweet pepper fruits in an enriched 50–75% ammonium–sulfate protein fraction. Protein samples (240 µg per lane) were separated by non-denaturing polyacrylamide gel electrophoresis (PAGE; 8% acrylamide), and activity was detected using the NBT method (left). NADP-ME isozymes were labeled I–IV. Densitometric analysis of these isozymes and their relative quantification (%) were conducted using the ImageJ program according to the isozyme profiles obtained (right).
