Summary:Generally, the present invention relates to the field of antibodies. In particular, it relates to multispecific antibodies, e.g. bispecific antibodies, which are modified such that the desired chain pairing takes place and/or can be selected for. Specifically, this is achieved by using different dimerization domains for light chain pairing. The invention further relates to nucleic acids encoding for these antibodies, expression vectors comprising these nucleic acids, cells expressing them, and further to pharmaceutical compositions comprising the antibodies. The invention also relates to methods of isolating the antibodies. Generalmente, la presente invención se refiere al campo de anticuerpos. En particular, se refiere a anticuerpos multiespecíficos, por ejemplo, anticuerpos biespecíficos, que se modifican de manera que el emparejamiento de cadenas deseado tiene lugar y/o puede seleccionarse. Específicamente, esto se consigue usando diferentes dominios de dimerización para el emparejamiento de cadenas ligeras. La invención se refiere además a ácidos nucleicos que codifican estos anticuerpos, vectores de expresión que comprenden estos ácidos nucleicos, células que los expresan, y además a composiciones farmacéuticas que comprenden los anticuerpos. La invención también se refiere a métodos para aislar los anticuerpos.
