There are three major steps for the generation of FAE bispecific antibody. Firstly, two IgG antibodies are separately expressed in mammalian cell lines. Meanwhile, a single residue mutation is introduced into the third constant (CH3) domain of each antibody. Then these antibodies are purified through standard protein recovery and purification procedures. Finally, bispecific antibody is produced by recombining of these two antibodies. Our FAE bispecific antibody has first-class quality with high yield (typically >95%) which can fully meet your demands.
Our FAE technology platform can also satisfy the requirement for large-scale manufacturing, which can generate at 0.5 kg/25 L scale. In addition, our FAE bispecific antibody products are stable for more than 15 months at 4°C.
