Analysis of fermentation supernatants during the two-phase fermentation process for the production of VAMAX2. (a) Proteins in 15 µL supernatant were separated by LDS-PAGE and stained with SimplyBlue SafeStain. (b) The proteins separated above were further analyzed by immunoblotting using the reduction-sensitive mAb 4G2. Times above the lanes indicate the elapsed hours of each process phase. M: protein marker. EoB: end of batch-phase. V2: target protein VAMAX2.
