Abstract

<p>(A) Rat muscle extracts were separated by SDS PAGE and probed by immunoblotting as described in the Methods. The analysis was limited to 15 animals (n = 8 biome enriched; lanes E1 through E8, and n = 7 biome depleted; lanes D1 through D7) due to size constraints of the gel. A control strip with no serum is labeled “C”, and indicates reactivity of the anti-IgM conjugate with muscle-derived antigens. (B) The number of bands recognized by natural IgM in individual sera (p = 0.0089) and the total reactivity of natural IgM from each serum sample (p = 0.0093) are shown, with the bars indicating the mean and standard error. (C) The distribution of bands as a function of band size is shown. For this analysis, the average number of bands in biome depleted and biome enriched rats (Y-axis) was plotted on linear and log scales (main figure and figure inset, respectively) versus different band sizes (X-axis).</p
