The foundation for most BsAbs is one antigen binding site that binds the CD3 receptor, which activates the cytotoxic T lymphocytes, and another antigen site that binds a tumour specific antigen and promotes the destruction of tumour cells:
Tumour specific antigen we can support
TNF, IL1, IL4, IL14, IL17, IL23
Antibody Analytics have developed a novel suite of SPR assays to assess your molecule in a multitude of ways no matter what flavour your bispecific comes in. These assays will provide data so that you can have confidence that your molecule is performing as expected.
