WebIgM constitutes about 5–8% of total serum immunoglobulins. It is a heavy molecule with a molecular weight varying from 900,000 to 1,000,000 Da. It has a half-life of 5 days. IgM antibodies are short-lived and disappear early as compared to IgG. The presence of IgM antibody in serum, therefore, indicates recent infection. Immunoglobulins are composed of light chains and heavy chains. The light chain (λ or κ) is a protein of ~220 amino acids, composed of a variable domain, VL (a segment of approximately 110 amino acids), and a constant domain, CL (also approximately 110 amino acids long).
