Flashcards in Immunoglobulin (antibody) classes Deck (16):

Protects against bacteria and viruses by enhancing phagocytosis, neutralising toxins and triggering complement

The second antibody involved in the primary response?
First/most abundant antibody in the secondary response?
Mainly found in sweat, tears, saliva, mucus, breast milk and GI secretions
Levels decrease during stress, lowering resistance to infection
Type III reactions involve antigens, antibodies and complement - which antibody?
Occurs as pentamers
First antibody class to be secreted by plasma cells after initial exposure to any antigen
In blood plasma, anti-A and anti-B antibodies of the ABO blood group, which bind to A and B antigens during incompatible blood transfusions are also?

Mainly found on the surfaces of B cells as antigen receptors
