title: C3b receptors on the cell membranes of the stimulated mouse macrophages. An immunohistochemical study.
abstract: C3b receptors were visualized on the cell membranes of stimulated mouse peritoneal macrophages (Mø) by the incubation with cross-reacting swine C3 with proof of this latter by FITC- or HRP-conjugated rabbit anti-swine-C3 antibody. The FITC-conjugate produced a granular and spotty fluorescence. In ultrastructure, the HRP-conjugate revealed minute dense areas of reaction product, whose modest numbers were seen in both aldehyde-prefixed and non-prefixed cell samples.
