Background
Immunoglobulin G (IgG) is the most abundant protein in the serum which accounts for 75% of the total immunoglobulins in the plasma of healthy individuals. IgG is a major effector molecule of the humoral immune response in humans and provides defense against parasitic invasion. IgG molecules (Fc portion) react with Fc-gamma receptors that are present on the surfaces of macrophages, neutrophils, natural killer cells, and can activate the complement system. IgG is produced in a delayed response to an infection and can be retained in the body for a long time. IgG is the major class of the five classes of immunoglobulins (IgM, IgD, IgG, IgA, and IgE) in human beings. These closely related glycoproteins, composed of 82–96% protein and 4–18% carbohydrate, differ in heavy chain structure and have unique profile with respect to antigen binding, immune complex formation, complement activation, triggering of effector cells and placental transport. IgG can be further divided into four subclasses, IgG1, IgG2, IgG3, and IgG4, based on their relative prevalence in human serum. The IgG concentration in normal human serum ranges from 6 mg/ml to 18 mg/ml. The relative abundance of the different immunoglobulin classes is generally constant in mature adults. Changes in the relative abundance of the different classes typically specify immunological disorders or disease states. For example, congenital and acquired immunodeficiency leads to significantly reduced levels of IgG, while hepatitis, cirrhosis, and most autoimmune diseases increase the levels of IgG. Thus, an accurate quantitation of IgG in plasma or serum is essential for diagnostic studies, as well as for monitoring the efficacy of treatment regimens.

Shipping & Handling
No test method can provide total assurance that the hepatitis B virus, hepatitis C virus, human immunodeficiency virus, or any other infectious agents are absent. Thus, all blood products, including purified proteins derived from human blood sources, should be handled at Biosafety Level 2 as recommended by the CDC\NIH manual entitled Biosafety in Microbiological and Biomedical Laboratories for potentially infectious human serum, blood specimens or proteins derived from same. Source material for the human blood product supplied to your facility has been tested for the detection of HIV antibody, Hepatitis B surface antigen, antibody to Hepatitis C, HIV 1 antigen(s), antibody to HTLV - I/II, and syphilis by FDA guidelines. All units were found to be non-reactive/negative for these tests. All human blood source material is collected in FDA licensed centers and is tested with FDA approved test kits.; This product is for research use only and is not intended for therapeutic or diagnostic applications.
