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. WebELISAs are typically performed in 96-well or 384-well polystyrene plates, which passively bind antibodies and proteins. It is this binding and immobilization of reagents that makes ELISAs easy to design and perform.
Web1.The Fc region is used as binding site for different immune system cells after the opsonisation of a pathogen. 2.Complement protein C1 binds to Fc region of antibody bound to an antigen to trigger classical complement pathway which leads to destruction of that antigen-antibody complex or opsonised pathogen.
