IgM is the third most abundant human immunoglobulin. IgM is also the first human immunoglobulin to be made by a fetus and virgin B cells which are challenged with antigen. Immunoglobulin M (IgM), which is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection. Immunoglobulin E (IgE), which is associated mainly with allergic reactions (when the immune system overreacts to environmental antigens such as pollen or pet dander). IgG is the most common class of immunoglobulin.

Immunoglobulin m

Antikroppar eller immunoglobuliner är Y-formade proteiner som används av kroppens immunsystem för att identifiera främmande ämnen, till exempel virus, bakterier eller parasiter. Als Immunglobulin M (IgM) bezeichnen Mediziner eine bestimmte Antikörper-Klasse. Jeweils fünf einzelne IgM lagern sich zu einer größeren Struktur zusammen – einem sogenannten Pentamer. Lesen Sie hier, welche Funktionen das Immunglobulin M im Rahmen der Körperabwehr erfüllt und in welchen Fällen der IgM-Wert im Blut erhöht oder erniedrigt ist. Immunoglobulins Immunglobuliner Svensk definition. Glykoproteiner som förekommer i blod (antikroppar) och andra vävnader.

Immunoglobulin M () is constructed of five or six units (i.e. mostly as pentamers but also hexamers occur) which are each comprised of two heavy-chains (mu-chains) and two light chains, bound together by disulfide bonds and a so-called J-chain. A J-chain is usually, but not always, found in pentameric but not in the hexameric form.

This test is used to evaluate a person’s immune system.

This flexible hinge (found in IgG, IgA and IgD, but not IgM or IgE) region allows the distance between the two antigen-binding sites to vary. Immunoglobulin M–producing multiple myeloma (IgM MM) is exceedingly rare, accounting for less than 1% of all myeloma cases.
