Claim:
A kit for delivering a diagnostic agent, a therapeutic agent, or a diagnostic agent and a therapeutic agent comprising: A) a bispecific antibody or antibody fragment having at least one arm that binds to a targeted tissue and at least one other arm that binds to a targetable conjugate, wherein said arm that binds a targetable conjugate is a 679 antibody or fragment thereof having the light chain complementarity determining region (CDR) sequences CDR1 (KSSQSLFNSRTRKNYLG, residues 24-40 of SEQ ID NO:2), CDR2 (WASTRES, residues 56-62 of SEQ ID NO:2) and CDR3 (TQVYYLCT, residues 95-102 of SEQ ID NO:2) and the heavy chain CDR sequences CDR1 (IYTMS, residues 30-34 of SEQ ID NO:4), CDR2 (TLSGDGDDIYYPDSVKG, residues 49-65 of SEQ ID NO:4) and CDR3 (VRLGDWDFDV, residues 98-107 of SEQ ID NO:4); B) a targetable conjugate comprising a histamine-succinyl-glycine (HSG) hapten that binds to the 679 antibody or fragment thereof, wherein the targetable conjugate is attached to at least one diagnostic or therapeutic agent.
