These proteins contain framework regions surrounding their hypervariable regions.
Affilins and affimers are engineered to mimic the function of these proteins. These proteins contain framework regions surrounding their hypervariable regions. Papain [pap-ANE] can cleave these proteins into two Fab fragments and one Fc fragment. These proteins' varying affinities are caused by somatic hypermutation. In a Western blot, both primary and secondary types of these proteins are used to tag the protein of interest. These proteins, which can be produced monoclonally or polyclonally from B cells, are Y-shaped molecules made of two light chains and two heavy chains. For 10 points, name these proteins that bind to antigens as part of the immune system response.
