Absence of detection of intestinal MUC13 (lane 3) by anti-mucin 13 antibodies in the purified high molecular weight (MW) fraction of F4ab/acR⁺ BBMVs.

Abstract

<p>Purification occurred by anion exchange chromatography followed by gel filtration chromatography. Strong binding of F4ac fimbriae to the high MW glycoproteins can be seen in lane 2. Lane 1: protein standard.</p
