Question
Chapter 12, Problem 30SAE
Summary Introduction
To review:
The five classes of immunoglobulins (Ig). Also give the name of the one that is most likely to be attached to a B (lymphocytes maturing in the bone marrow) cell membrane, abundant in the plasma, important in allergic responses, the first Ig released during primary response and crosses the placental barrier.
Introduction:
Immunoglobulins or antibodies are grouped into five isotypes that differ in the type of heavy chain present. These make a part of the humoral immunity under the adaptive or specific immune system of the body.
