isotype

isotype
An antigenic determinant (marker) that occurs in all members of a class or subclass in the heavy chains of an immunoglobulin or in the type and subtype of light chains of an immunoglobulin molecule. Whereas a given allotypic marker or determinant is thought to occur in only one subclass, an antigenic marker that is isotypic in one subclass may also occur as an allotypic marker in another subclass. [iso- + G. typos, model]
