Immunoglobulin G (IgG) is a type of antibody. Representing approximately 75% of serum antibodies in humans, IgG is the most common type of antibody found in blood circulation . [ 1 ] IgG molecules are created and released by plasma B cells .
Each antibody binds to a specific antigen in a highly specific interaction analogous to a lock and key.. An antibody (Ab) or immunoglobulin (Ig) is a large, Y-shaped protein belonging to the immunoglobulin superfamily which is used by the immune system to identify and neutralize antigens such as bacteria and viruses, including those that cause disease.
Antibodies or Immunoglobulins are glycoproteins found within blood and lymph. Structurally, antibodies are large Y-shaped globular proteins. In mammals, there are five types of antibodies: immunoglobulin A, immunoglobulin D, immunoglobulin E, immunoglobulin G, and immunoglobulin M.
In secretory IgA, the form found in secretions, polymers of 2–4 IgA monomers are linked by two additional chains; as such, the molecular weight of slgA is 385kD. One of these is the J chain (joining chain), which is a polypeptide of molecular mass 15kD, rich with cysteine and structurally completely different from other immunoglobulin chains ...

kappa (κ) chain, encoded by the immunoglobulin kappa locus (IGK@) on chromosome 2 (locus: 2p11.2) lambda (λ) chain, encoded by the immunoglobulin lambda locus (IGL@) on chromosome 22 (locus: 22q11.2) Antibodies are produced by B lymphocytes, each expressing only one class of light chain. Once set, light chain class remains fixed for the life ...
This shows the levels of albumin and the different immunoglobulins. The serum protein electrophoresis test measures the number of proteins in the serum part of a blood sample. The normal ranges to check for the serum globulin would be about 2.0 to 3.5 grams per deciliter then for the immunoglobulins A, M, and G have different ranges.
μ – IgM; There are also two light chain isotypes κ and λ; however, there is no significant difference in function between the two. Thus an antibody isotype is determined by the constant regions of the heavy chains only. [1] IgM is first expressed as a monomer on the surface of immature B cells.
