immunoglobin G comprised of a tetramer containing two L chains and two H chains.
a class of immunoglobulins that include the most common antibodies circulating in the blood of higher vertebrates and are active esp. against proteins foreign to the body such as those found in bacteria. There are four subclasses of this immunoglobin[close window
The most common serum antibody. It can pass from mother to fetus during pregnancy, and diffuse across mucosal surfaces. IgG is also present in vaginal secretions, in higher concentrations than sIgA.
antibodies IgG is the most abundant of the circulating antibodies. It readily crosses the walls of blood vessels and enters tissue fluids. IgG also crosses the placenta and confers passive immunity from the mother to the fetus. IgG protects against bacteria, viruses, and toxins circulating in the blood and lymph.
one of the five major classes of immunoglobulins; the main antibody defense against bacteria
This is a protein in the blood produced by B lymphocytes (CD19+). It is an antibody that is present primarily in the lymph system. It is produced by IgM (Immunoglobulin) that resides in the blood. One IgM produces five IgG antibody molecules in a balanced system. It is a Y shaped molecule consisting of two heavy and two light chains, each having variable and constant regions. The variable regions determine the fit with the antigen that initiated the response like a key- in -lock situation.
Predominant antibody type in blood.
A specific immunoglobulin class that binds an antigen. IgG is the major immunoglobulin of the blood, lymph, cerebrospinal and peritoneal fluids.
most abundant antibody in blood
One of many antibodies present in blood serum which is usually indicative of a recent or remote infection. IgG is most prevalent about 3 weeks after an infection begins.
abbreviation, gamma globulin. Component of blood serum (plasma) containing antibodies.
the most abundant and common of the immunoglobulin.IgG functions mainly against bacteria and some viruses. It is the only antibody that is capable of crossing the placenta.
Most abundant Ig with four subclasses in humans that perform different functions one of which is complement pathway activation (both classic and alternate pathways). See "How is Lupus Diagnosed?"
