the binding affinity of igg for the peritoneal macrophages ( ka = 5.9 +/- 1.6 x 10 ( 5 ) l/m ) was comparable to that recorded with alveolar macrophages ( 7.6 +/- 1.8 x 10 ( 5 ) l/m , arend & mannik , 1973 ) but the number of receptor sites per peritoneal cell ( 4.6 +/- 2.1 x10 ( 6 ) ) was about four-fold greater than on the latter .
