Figure 7From: Influence of pH control in the formation of inclusion bodies during production of recombinant sphingomyelinase-D in Escherichia coli Differential spectra of Congo-Red (CR) binding to rSMD IBs obtained from controlled (A) and uncontrolled pH cultures (B). The rSMD IBs were isolated at 1, 3, 5 and 20 h post-induction. CR spectra were obtained in the presence of IB showing the absorbance shift at ~575 nm. In insets, the spectra for Congo red alone are shown.Back to article page
