the reliability of this approach was attested to by the fact that iga immunocytes in all secretory tissues investigated ( salivary , mammary and lacrimal glands ; nasal and intestinal mucosae ) expressed j-chain ( 87-97 % ) and sc affinity ( 84-87 % ) in comparable proportions , indicating that almost 90 % of the cells were engaged mainly in dimer production .
