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.”””,Fc (human):CD40L (soluble) (mouse)

Source |
Produced in HEK 293 cells. The extracellular domain of mouse CD40L (CD154) (aa 115-260) is fused at the N-terminus to the Fc portion of human IgG1 and a linker peptide (20 aa). |
Specificity |
Binds to human and mouse CD40. |
Technical Info / Product Notes |
Historical data has shown that Fc (human):CD40L (mouse) stimulates the proliferation of mouse B cells and dendritic cells. Note: Does not require an enhancer. |
