Purification and quantification of OPGs from Y. enterocolitica. OPGs were extracted from wild-type, ΔopgGH and ΔopgGH-PBADopgGH strains grown to the exponential phase in LNNS medium supplemented with 0.6 g/L L-arabinose. (A) Gel filtration chromatography of OPGs. (B) Quantification of purified OPGs. The data are presented as the mean ± SD of at least three independent experiments. An asterisk indicates a significant difference with ****P < 0.0001.
