Human IgG1, kappa - Isotype Control antibody,Abcam,AB288147

Target data The protein expressed by the IGHG4 gene is part of the constant region of immunoglobulin heavy chains. Immunoglobulins, or antibodies, are glycoproteins produced by B lymphocytes that can be membrane-bound or secreted. During humoral immunity's recognition phase, membrane-bound immunoglobulins act as receptors. When they bind a specific antigen, they trigger B lymphocytes to undergo clonal expansion and differentiate into plasma cells that secrete immunoglobulins. These secreted immunoglobulins then mediate the effector phase of humoral immunity to eliminate the bound antigens. Each immunoglobulin possesses two antigen binding sites, formed by the variable domains of a heavy chain and an associated light chain, allowing for high affinity binding to specific antigens. These variable domains undergo V-(D)-J rearrangement and may experience somatic hypermutations, facilitating affinity maturation after antigen exposure and selection.
