What is antibody mediated immune suppression?

Prophylactic administration of RhIg to RhD− women successfully prevents the generation of de novo anti-RhD antibodies associated with pregnancy through a process termed antibody-mediated immune suppression (AMIS),9-13 whereby passively acquired antibody inhibits sensitization to a given antigen.

What are the 5 types of antibodies and function?

5 types of antibodies, each with a different function There are 5 types of heavy chain constant regions in antibodies (immunoglobulin) and according to these types, they are classified into IgG, IgM, IgA, IgD, and IgE. They are distributed and function differently in the body.

Which antibody type is largest?

IgM is the largest antibody and the first one to be synthesized in response to an antigen or microbe, accounting for 5% of all immunoglobulins present in the blood. IgM typically exists as polymers of identical subunits, with a pentameric form as the prevalent one.
