Figure Lengend Snippet: FIG. 3. Analysis of Triton X-114 extracts by preparative IEF and determination of the N-terminal sequence of the 29-kDa protein. The aqueous phases of the Triton extracts were separated into 20 fractions by preparative IEF with the Rotofor cell. Each fraction was analyzed by SDS-PAGE (A) and immunoblotting (B). The gels were stained with Coomassie blue. The PVDF membrane was incubated with patient sera and visualized with anti-human IgM. Lane 1, pooled fractions from fractions 1 to 3; lanes 2, fraction 5; lanes 3, fraction 6; lanes 4, fraction 7; lanes 5, pooled fractions 11 and 12; lanes 6, pooled fractions 17 and 18; lanes 7, pooled fractions 19 and 20; lanes 8, Triton X-114 extract, aqueous phase.
