Inability of mice with a defect in B-lymphocyte maturation to respond to phosphorycholine on immunogenic carriers.

Mice with the CBA/N defect are unresponsive to the hapten phosphorylcholine (PC) even when presented on a variety of immunogenic carriers. Since these mice have the variable region gene for PC, their inability to respond may reflect deletion or suppression of the line of B lymphocytes which is responsible for the anti-PC response.
