Antibodies are described which can bind to a member of a binding pair and to a macromolecule in which the capability of binding to the macromolecule is reversibly inhibited by the presence of a photocleavable moiety. Favoured antibodies are bispecific antibodies, for example against a tumour cell and against an enzyme or a killer cell in which the capability of binding to the enzyme or the killer cell is inhibited until the photocleavable moiety is removed on irradiation.
描述了一种能够结合到结合对的成员和到一种大分子的
抗体,其中结合到大分子的能力通过光解离性基团的存在而可逆地受到抑制。优选的
抗体是双特异性
抗体,例如针对肿瘤细胞和针对酶或杀伤细胞的
抗体,在这些
抗体中,结合到酶或杀伤细胞的能力在光照作用下直到光解离性基团被去除之前都受到抑制。
