The C region of the heavy chains mediates the functions of the soluble form of antibodies. The C regions of IgA, IgD, and IgG contain three Ig domains, whereas the C regions of IgE and IgM contain four Ig domains. Webone variable domain (V L) that is important for binding antigen The approximate length of a light chain protein is from 211 to 217 amino acids. [3] The constant region determines what class (kappa or lambda) the light chain is. [8] The lambda class has 4 subtypes ( 1, 2, 3, and 7 ). [8] In pathology [ edit] the buttler bidet
