Rabbit anti-mouse brain serum (RAMBS): lack of specific inhibition of late committed erythroid stem cells in culture (CFU-E).

Heterologous antisera to mouse brain tissue have activity against mouse pluripotent hemopoietic stem cells (CFU-S), but not against granuloid/macrophage committed precursor cells (CFU-C). In these studies we show that anti-mouse brain serum raised in a rabbit does not possess specific activity in vitro against late committed erythroid stem cells (CFU-E).
