Figure 4From: Screening and identification of genetic loci involved in producing more/denser inclusion bodies in Escherichia coliDensity gradient analysis of mixed cultures of induced QC1101 and QC1525. Top panel of the figure shows the banding patterns of individual cultures and the mixed cultures on 70% percoll density gradient. I, induced. Arrows indicate the bands that were extracted for SDS-PAGE analysis. Lower panel shows the SDS-PAGE analysis of the extracted bands. Numbers on the lanes on SDS-PAGE correspond to the numbers of bands on density gradient. Arrowheads show HC124 peptide, while arrows show HC415 peptide in the SDS-PAGE gel.Back to article page
