Figure: Proliferation of mouse B cells induced by Fc (human):CD40L, Soluble (mouse) (rec.) (Prod. No.
ALX-522-072).
Method: Splenocytes from Balb/c mice were purified on B220 magnetic beads using the MACS system. The resulting B cells were put in culture at a cell density of 70’000 cells/well in a 96-well plate. Cells were activated with the indicated concentrations of Fc (human):CD40L, Soluble (mouse) (rec.). After 36 hours, 0.5µCi of 3H-Thymidine/well was added. Cells were pulsed for 10 hours, then freeze-thawed, harvested and counted."
