What Is an Antibody Isotype?

Isotype: Ig antigen specificity common to all individuals in the same genus, which can induce the production of corresponding antibodies in the xenograft. Isotype antigen specificity is mainly located in the c region of Ig, including class and subclass, type and subtype.

Immunological isotypes:
An immunoglobulin isotype refers to a genetic change or difference in the type of immunoglobulin heavy chain.
Humans have nine isotypes:
Heavy chain -IgA 1, 2
-IgD
-IgG 1, 2, 3, 4
-IgE
-IgM
Light chain
lambda
Immunoglobulin type switching can change the type of the heavy chain, but not the light chain.
