IgG is an immunoglobluin monomer, meaning that it is one immunoglobulin that is small enough to cross the placenta. An example would be the Rh antibody that causes isoimmunization between Rh negative mothers and Rh positive fetuses. In constrast, ABO blood group immunoglobulins are IgM which is a pentamer, meaning it is composed of 5 immunoglobulins and is too large to cross the placenta.

Which antibodies can cross placental barrier?
IgG is the only antibody small enough to cross he placenta.
What is the percentage of Immunoglobulin G in the plasma?
IgG, is the predominant Ig class present in human plasma. Produced as part of the secondaryimmune response to an antigen, it is approximately 75% of total serum Ig. IgG is the only class of Ig that can cross the placenta in humans.
Why is my immunoglobulin G high?
I have sarciodosis
What is immunoelectrophoresis?
also called gamma globulin electrophoresis, or immunoglobulin electrophoresis, is a method of determining the blood levels of three major immunoglobulins: immunoglobulin M (IgM), immunoglobulin G (IgG), and immunoglobulin A (IgA).
What is the most common type of antibody found in plasma?
Immunoglobulin G; it makes up 80% of the Immunoglobulin content in the bloodstream
What are the classes of antibodies?
There are five immunoglobulin classes (isotypes) of antibody molecules found in serum: IgG, IgM, IgA, IgE, and IgD. IgA (immunoglobulin A) IgD (immunoglobulin D) IgE (immunoglobulin E) IgG (immunoglobulin G) IgM (immunoglobulin M)
What is normal immunoglobulin g?
Normal range is between 700 and 1600.
What is the most abundant type if immunoglobulin?
The answer is IgG
In the primary response to an antigen the first class of antibody to be secreted is?
The class of immunoglobulin to respond to the fist exposure of an antigen is immunoglobulin class M (IgM). While Immunoglobulin G (IgG) would predominate on the second exposure.
What immunoglobulin Ig is mainly responsible for resistance against viruses bacteria and bacterial toxins?
The immunoglobulin G (IgG) is the most important for humans; see also the link below.
What class of antibody is produced in the primary immune response?
The class of immunoglobulin that is produced in the primary immune response is Immmunoglobulin M (IgM). On secondary exposure, the class that predominates would be Immunoglobulin G (IgG).
