IgG subclass distribution of anti-sheep red blood cell plaque-forming cells in mice with the CBA/N defect.

The IgG subclass distribution of anti-sheep red blood cell (SRBC) plaque-forming cells (PFC) in CBA/N, CBA/Ca, and (CBA/N X CBA/Ca)F1 male and female mice was examined. The results show that the X-linked immunodeficiency of CBA/N mice affects the development of anti-SRBC PFC of all IgG subclasses tested.
