IgAIgM
IgAIgM is a term used in a limited set of immunology discussions to describe a hypothetical immunoglobulin that combines features of IgA and IgM. It is not part of the standard human immunoglobulin isotype repertoire and is not recognized as a naturally occurring antibody class. In some discussions, IgAIgM denotes either a theoretical bifunctional or bispecific construct engineered for research, or a conceptual category for B-cell states involving atypical co-expression patterns of IgA- and IgM-related components.
Structural considerations for IgAIgM are speculative. Possible interpretations include a single polypeptide that blends IgA-like and
Production and detection, in the context of IgAIgM, are contingent on the approach chosen. If used as
Function and potential applications remain hypothetical. Their proposed advantages might include broader mucosal interaction (associated with
