WebAs is well known in the art, a variety of natural proteins bind Fc and antibodies, and these proteins can find use for purification of the anti-HER2 biparatopic antibodies described herein. For example, the bacterial proteins A and G bind to the Fc region. Likewise, the bacterial protein L binds to the Fab region of some antibodies. WebApr 14, 2024 · Here, we designed antibody-like molecules by creating IgG Fc fusions with PGLYRP1. In this study, we found that mouse IgG2a-Fc fusion with the extracellular region of PGLYRP1(PGLYRP1-Fc) binds to the macrophages and inhibited the production of pro-inflammatory cytokines. The fragment crystallizable region (Fc region) is the tail region of an antibody that interacts with cell surface receptors called Fc receptors and some proteins of the complement system. This property allows antibodies to activate the immune system. In IgG, IgA and IgD antibody isotypes, the Fc region is composed of two identical protein fragments, derived from the second and third constant dainty gold wedding band
