In mammals, antibodies are divided into five isotypes: IgG, IgM, IgA, IgD and IgE, antigens: Isotype Heavy chain Light chain MW (kDa) Structure Function
antibody structure and isotypes
This region is called the Fc (Fragment, crystallizable) region, and is composed of two heavy chains that contribute two or three constant domains depending on the class of the antibody By binding to specific proteins the Fc region ensures that each antibody generates an appropriate immune response for a given antigen

19 déc 2000 · These so-called heavy-chain antibodies (HCAbs) bind antigen solely with one single variable domain, referred to as VHH Obviously, the appearance of HCAbs requires the acquisition of multiple events to allow their generation and maturation into functional molecules and opens up new perspectives in antibody engineering

What is the function of the heavy chain antibody?
Remarkably, these heavy chain antibodies are functional in antigen binding and reach high titers and affinities after immunizing a camelid. Antigen recognition by HCAbs is mediated by one single variable domain, referred to as VHH.What is the function of heavy chain and light chain?
Heavy chain and light chain are two subunits of an antibody. Heavy chain is the large polypeptide subunit of an antibody, while light chain is the small polypeptide subunit of an antibody. So, this summarizes the difference between heavy chain and light chain.What is heavy chain in immunology?
A heavy chain is the large polypeptide subunit of a protein complex, such as a motor protein (e.g. myosin, kinesin, or dynein) or antibody (or immunoglobulin). A typical antibody is composed of two immunoglobulin (Ig) heavy chains and two Ig light chains.- 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.
