Additional file 1: Figure S1. of Comparison of lipopolysaccharides composition of two different strains of Helicobacter pylori

An inverted overlay of LPS composition analysis from H. pylori strains, SS1 and G27. The aqueous (a) and phenol (b) fractions depicts the differences in peak heights of SS1 (black) and G27 (red) using GC-MS analysis of FAME and Tri-Sil FAME derivatives. Figure S2. GC-MS analysis of E. coli strain 0113. E. coli LPS was analyzed as standard reference. (PDF 530 kb)
