Technical Info/Product Notes:
Historical data has shown that CD40L stimulates growth of B cells. The activity of rhsCD40L increases 1'000-fold (stimulation in the ng/ml range) in the presence of cross-linking enhancer (see Set Prod. No. ALX-850-064). For stimulation of mouse cells via CD40 use CD40L, Soluble (mouse) (recombinant) (Prod. No. ALX-522-070 or ALX-850-075).

Figure 2: Stimulation of B cells by CD40L, Soluble (human) (rec.). Dose dependent costimulation of CD19+ cells by CD40L in the presence of 10ng/ml of IL-4 and of 2µg/ml anti-µ antibodies. Note that in the presence of enhancer (Prod. No. ALX-804-034), the activity of CD40L is increased >1’000 fold.Method: CD19+ cells were incubated in 96-well plates (105 cells/well in 100µl RPMI supplemented with 10% FCS) for 72 hours in the presence of 10ng/ml IL-4, 2µg/ml of goat anti-human µ chain antibody and with the indicated concentration of CD40L in the presence and absence of 1µg/ml enhancer (Prod. No. ALX-804-034). Cells were pulsed for an additional 6 hours with [3H]thymidine (1µCi/well) and harvested. [3H]thymidine incorporation was monitored by liquid scintillation counting."
