Adoptive transfer of immune serum into naive BALB/c mice significantly delays tumor growth (P = .018).
Sera taken from mice 6 weeks after immunization with bsAb BiLu (▪) and irradiated tumor cells were pooled and transferred (300 μL) together with 3 × 105 viable A20 cells intravenously into naive BALB/c mice. The control group (+) received serum of naive, untreated mice in combination with tumor cells.
