Molecular identification of PAL-E, a widely used endothelial-cell marker

Abstract excerpt

The pathologische anatomie Leiden-endothelium (PAL-E) antibody has been used for almost 20 years as a specific marker for vascular endothelial cells. Due to the fact that this antibody works only in very limited applications, the molecular identity of PAL-E has remained unknown. In this work, we demonstrate by double stainings, cross-immunoprecipitations, and transfectants that the PAL-E antigen is identical with...
