Figure 3From: Rivoflavin may interfere with on-line monitoring of secreted green fluorescence protein fusion proteins in Pichia pastorisEmission spectrum from retained and filtered culture supernatans. Emission spectrum, given as fluorescence arbitrary units, excited at 488 nm from control strain cultivation samples (black) and GFP-fusion expressing strain cultivation samples (green line). Retained fractions (A), and corresponding filtrated fractions (B).Back to article page
