Fig. 1. Analysis of Cav-2 expression in Caco-2 cells. Microsomal fractions of
Caco-2 and Huvec (endothelial) cells were analyzed by SDS-PAGE and western
blotting. Cav-2 was undetectable in Caco-2 cells but strongly expressed in
endothelial cells using an anti-human Cav-2. A molecular mass marker is
indicated on the left.
