WebNational Center for Biotechnology Information WebOct 8, 2015 · In eukaryotes, such as yeast or mammalian cells, which have large genomes, a higher recombinant protein expression can be troublesome. Comparatively, in the Escherichia coli (E. coli) expression system, although the expression is induced with isopropyl β-d-1-thiogalactopyranoside (IPTG), studies have shown low expression levels … WebIPTG uptake by E. coli can be independent of the action of lactose permease, since other transport pathways are also involved. [1] At low concentration, IPTG enters cells through lactose permease, but at high concentrations (typically used for protein induction), IPTG can enter the cells independently of lactose permease.
