antigenic determinant is defined as a region of an antigen that makes contact with the antigen-combining region on an antibody. Which statement is true for Anti-isotype antibodies?

#Unit 4. Cell Communication and Cell Signaling
  1. Antigenic determinants that are allele specific—small differences in the constant region of light and heavy chains that vary among individuals.
  2. Antigenic determinants characteristic of a particular antigen combining site. Each antibody will have its own characteristic idiotypic determinants made up of residues from the heavy and light chains that contribute to the antigen-binding regions.
  3. Antigenic determinants specific to each heavy chain class
  4. Papain-generated fragment of antibodies consisting of the paired CH2CH3 (and, for IgM and IgE, CH4) domains
