Product Specification
SPECIES CROSSREACTIVITY:   
Human
 
SOURCE/HOST:   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.
 
CONCENTRATION:   CD40L: 0.1mg/ml after reconstitution.
Enhancer: 1mg/ml after reconstitution.
 
KIT/SET CONTAINS:   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.
 
PURITY:   ≥95% (SDS-PAGE).
 
FORMULATION:   Lyophilized. Contains PBS.
 
RECONSTITUTION:   Reconstitute CD40L with 100µl and each vial of enhancer with 50µl sterile water. Further dilutions should be made with medium containing 5% fetal calf serum or carrier protein.
 
SPECIFICITY:   

CD40L binds to human CD40.

 
APPLICATION:   

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).

 
SHIPPING:   SHIPPED ON BLUE ICE
 
LONG TERM STORAGE:   -20°C
 
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.

General Information

Background/Technical Information   

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.
