Immunity Lecture Flashcards
Match the gamma globulin proteins secreted by plasma cells to their examples
lgE - Molecules active when a patient has allergies or parasites; causes histamine release.
lgA - In mucus to prevent entry of pathogens past the mucus membranes.
lgD - A molecule attached to the surface of B cells.
lgM - 1st antibody released; an agglutinator
lgG - The highest % of antibodies in plasma; it can cross the placenta
