The invention relates to an anti-CEA monoclonal antibody (named “806.077 antibody”) of murine origin and useful for the diagnosis and therapy of cancer. The antibody complementarity determining regions (CDRs) have the following sequences: heavy chain; CDR1 DNYMH, CDR2 WIDPENGDTE YAPKFRG, CDR3 LIYAGYLAMD Y; and light chain CDR1 SASSSVTYMH, CDR2 STSNLAS, CDR3 QQRSTYPLT. Humanised antibodies are described. The antibody is preferably in the form of a conjugate with either an enzyme suitable for use in an ADEPT system, especially a carboxypeptidase, or with a co-stimulatory molecule such as the extracellular domain of human B7.1.
本发明涉及一种抗 CEA 单克隆抗体(名为 "806.077 抗体"),该抗体来源于鼠类,可用于癌症的诊断和治疗。抗体互补性决定区(CDR)的序列如下:重链;CDR1 DNYMH,CDR2 WIDPENGDTE YAPKFRG,CDR3 LIYAGYLAMD Y;轻链 CDR1 SASSSVTYMH,CDR2 STSNLAS,CDR3 QQRSTYPLT。描述了人源化抗体。抗体最好是与适合用于 ADEPT 系统的酶(尤其是羧肽酶)或与共刺激分子(如人 B7.1 的胞外结构域)共轭的形式。
