This invention provides novel erbB2-binding internalizing antibodies. The antibodies, designated F5 and C1, specifically bind to c-erbB2 antigen and, upon binding, are readily internalized into the cell bearing the c-erbB2 marker. Chimeric molecules comprising the F5 and/or C1 antibodies attached to...http://www.google.com.au/patents/US7892554?utm_source=gb-gplus-sharePatent US7892554 - Internalizing ErbB2 antibodies
