Bispecific antibodies with binding specificities for two different antigens have prompted a lot of interest into their development and application. Currently, more than ten bispecific antibodies have been clinically validated for the treatment of various diseases, including cancers and inflammatory diseases. Intensive studies in antibody engineering drive the generation of different bispecific antibody formats that differ in size and shape. However, the most prominent formats, such as IgG-single-chain (sc) Fv or dual-variable domain (DVD) IgG, deviating from the natural IgG structure, may lead to manufacturing difficulties or increase the potential risk of immunogenicity. Thus, the recent efforts focus on the development of bispecific antibodies by Fc heterodimerization that maintain the native structure of the antibody IgG molecule. This review summarizes the various techniques and methods to generate bispecific antibody molecules with Fc heterodimerization, and discusses perspectives of their application.

01:28Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
01:10Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:25Antibody Structure and Classes
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
