Targeting of Multidrug-Resistant Human Ovarian Carcinoma Cells With
Anti-P-Glycoprotein Antibody Conjugates.

A monoclonal antibody (mAb) to P-glycoprotein (Pgp), UIC2, is used as a targeting
moiety for N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer/drug [(meso chlorin
e(6) mono(N-2-aminoethylamide) (Mce(6) ) or doxorubicin (DOX)] conjugates to
investigate their cytotoxicity towards the Pgp-expressing human ovarian carcinoma
cell line A2780/AD. The binding, internalization, and subcellular trafficking of
a fluorescein labeled UIC2 targeted HPMA copolymer are studied and show
localization to the plasma membrane with limited internalization. The specificity
of the UIC2-targeted HPMA copolymer/drug conjugates are confirmed using the
sensitive cell line A2780 that does not express Pgp.
