Figure 1: Stimulation of B-cell precursor (BCP) acute lymphoblastic leukemia by CD40L, Soluble (human) (rec.). Phenotypic characterization of unstimulated (left panels) and Cd40-stimulated (right panels) pre B ALL cells from a patient cultured on human bone marrow stroma layer for 48 hours. Histograms represent the fluorescence distribution by MAb to CD80 as analyzed by flow cytometry for a representative case.

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."

Product Details
Alternative Name:
CD154, TNFSF 5
Applications:
FUNC
Application Notes:
Can be used to activate human B cells and dendritic cells. Stimulates growth of human B cells. For stimulation of mouse cells via CD40 use MAb to CD40 (mouse) (FGK45) (Prod. No. ALX-805-046).
Species reactivity:
Human
Specificity:
CD40L binds to human CD40.
Purity:
≥95% (SDS-PAGE).
Contents:
10µg of CD40L, Soluble (human) (recombinant) (Prod. No. ALX-522-015) and 2x50µg of Enhancer for Ligands (Prod. No. ALX-804-034), which increases the biological activity of rhsCD40L at least 1'000-fold.
Formulation:
CD40L: Lyophilized. Contains PBS. Enhancer: Liquid. In PBS, pH 7.4, containing 50% glycerol. The formulation contains no antimicrobial preservatives.
Reconstitution:
Reconstitute CD40L with 100µl sterile water. Further dilutions should be made with medium containing 5% fetal calf serum or carrier protein.
Concentration:
CD40L: 0.1mg/ml after reconstitution Enhancer: 1mg/ml
Use/Stability:
Stable for at least 6 months after receipt when stored at -20°C.
Handling:
Avoid freeze/thaw cycles. After reconstitution, prepare aliquots and store at -20°C.
Shipping:
Blue Ice
Long Term Storage:
-20°C
Source:
Produced in E. coli. The extracellular domain of human CD40L (CD154) (aa 116-261) is fused at the N-terminus to a linker peptide (6 aa) and a FLAG®-tag.
Technical Info/Product Notes:
CD40L (Prod. No. ALX-522-015) and Enhancer for Ligands (Prod. No. ALX-804-034) should be incubated together for 30 min. at room temperature prior to cell application. Effects are typically best seen with 0.5-10µg/ml of CD40L together with 1-2µg/ml of enhancer. This may vary by cell type and experimental conditions.
