网页There are 5 classes of immunoglobulin, IgG, A, M, D and E, determined by their heavy chains. In normal serum, approximately 80% is IgG, 15% IgA, 5% IgM, with 0.2% IgD and trace IgE. Laboratory testing for immunoglobulins in peripheral blood typically detects the 3 major classes, IgG, A and M.
Difference Between IgM and IgG (with Comparison Chart) - Bio …
网页2017年3月25日 · Following are the key differences between IgM and IgG: Though both the antibodies (IgM and IgG) are proteins, made for fighting against antigens or foreign particles, IgM provides immediate response when an antigen enters the body while IgG responds later with the permanent eradication of antigen and its effect is lasting. Also, IgG helps in ...
Immunoglobulins Blood Test - Understand the Test & Your Results
网页An immunoglobulins test usually measures three specific types of immunoglobulins. They are called igG, igM, and IgA. If your levels of igG, igM, or IgA are too low or too high, it may be a sign of a serious health problem. Other names: quantitative immunoglobulins, total immunoglobulins, IgG, IgM, IgA testing.

Immunoglobulin G Antibody - an overview | ScienceDirect Topics
网页IgG is the most common isotype found in serum, comprising about 70% of the circulating antibody. IgG antibodies are usually of higher affinity than IgM antibodies and predominate in a secondary or memory immune response. In humans there are four subclasses of IgG: IgG1, IgG2, IgG3, and IgG4.
Structure, Function, and Therapeutic Use of IgM Antibodies
网页2020年10月13日 · Natural immunoglobulin M (IgM) antibodies are pentameric or hexameric macro-immunoglobulins and have been highly conserved during evolution. IgMs are initially expressed during B cell ontogeny and are the first antibodies secreted following exposure to foreign antigens.
