IMMG : The gamma globulin band as seen in conventional serum protein electrophoresis consists of 5 immunoglobulins. In normal serum, about 80% is immunoglobulin G (IgG), 15% is immunoglobulin A (IgA), 5% is immunoglobulin M (IgM), 0.2% is immunoglobulin D (IgD), and a trace is immunoglobulin E (IgE). Protection at mucosal surfaces through the secretion of antibodies is a phylogenetically ancient function. Mammals can produce high and low-affinity IgA against their commensal microbes via T-cell-dependent and T-cell-independent pathways to contribute to host microbial mutualism. Immunoglobulin A (IgA) er et antistof der primært findes i sekreter, hvor det spiller en væsentlig rolle for beskyttelse mod indtrængen af mikroorganismer.IgA får mikroorganismerne til at klumpe sammen, så de ikke kan trænge igennem slimhinden. Imunoglobulin juga dikenal sebagai antibodi. Mereka dibuat oleh sel plasma (sel darah putih).

Hence, the assessment of the immunoglobulin isotype can provide useful insight into complex humoral immune response.
