IMMUNE RESPONSES IN VITRO

Abstract
The suppressive effects of monospecific goat anti-mouse globulins on primary immunoglobulin class-specific plaque-forming cell responses in mouse spleen cell cultures were investigated. Anti-µ suppressed responses in all immunoglobulin classes, whereas anti-γ1 and anti-γ2 suppressed the γ1 and γ2 responses but not γM or γA responses, and anti-γA suppressed only γA responses. The mechanism of action of the anti-µ was studied in detail because of its suppression of responses in all immunoglobulin classes.
