Coomassie blue-staining (A) and silver-staining (B) of LPS extracted from B.melitensis 16 M. LPS was prepared by hot phenol-water extraction method and fractionated by SDS-PAGE electrophoresis, followed by commassie blue (A) or silver (B) staining. LPS banding is seen (B). The absence of band in commassie blue staining as shown in A indicates no contamination of purified LPS with bacterial proteins. Lane 1: LPS, Lane 2: Molecular weight marker
