Technical Data
IgG is a glycoprotein that is produced by plasma cells in response to an immunogen (1). It is the only class of immunoglobulins that can cross the placenta, which is mediated by a receptor on placental cells in the Fc region (1). Human IgG2 subclass has been identified to exist as an ensemble of distinct isoforms, designated IgG2-A, -B, and -A/B, which differ by the disulfide connectivity at the hinge region (2). IgG2-A is the known classic structure for the IgG2 subclass defined by structurally independent Fab domains and hinge region (3). IgG2-B is a structure defined by a symmetrical arrangement of a (C(H)1-C(L)-hinge)(2) complex with both Fab regions covalently linked to the hinge (3). IgG2-A/B represents an intermediate form, defined by an asymmetrical arrangement involving one Fab arm covalently linked to the hinge through disulfide bonds (3).
