The interaction of human apolipoprotein (apo-) E3 with heparin was examined using
heparin-Sepharose as a model system. The approach taken to determine the region of apo-
E that is responsible for binding to heparin was to identify apo-E monoclonal antibodies that
inhibited heparin binding, to determine the epitopes of the inhibiting antibodies, and finally
to examine the heparin binding of fragments containing the inhibiting antibody epitopes.
Three antibodies, designated 1D7, 6C5, and 3H1, were found to inhibit binding, suggesting …
