HEK-Blue™ CD40L Cells
CD40L Sensor Cells
HEK-Blue™ CD40L cells can serve to measure the bioactivity of CD40L through the secretion of embryonic alkaline phosphatase (SEAP) upon NF-κB activation following CD40 stimulation. These cells were generated by stable transfection of HEK293 cells with the human CD40 gene and an NF-κB-inducible SEAP construct. Binding of CD40L to its receptor CD40 triggers a signaling cascade leading to the activation of NF-κB and the subsequent production of SEAP. CD40L-CD40 interaction can be monitored by assessing the levels of SEAP using QUANTI-Blue™. HEK293 cells express endogenously the receptors for the cytokines IL-1β and TNF-α which share a common signaling pathway with CD40L. Consequently, HEK-Blue™ CD40L cells also respond to IL-1β and TNF-α. IL-1β- and TNF-α-mediated SEAP production can be blocked using neutralizing antibodies, such as anti-hIL-1β-IgA and anti-hTNF-α-IgA  respectively.
HEK-Blue™ CD40L cells are available in a kit containing anti-hCD40L-IgA.

Recombinant human CD40L
Recombinant Human CD40 Ligand
CD40 ligand, CD40L (also known as CD154, TRAP or gp39), is a type II transmembrane glycoprotein belonging to the TNF family. CD40L is predominantly expressed on activated CD4+ T lymphocytes. Recombinant human CD40L is a 149 amino acid, non-glycosylated protein. The approximate molecular mass of CD40L is 16.3kDa. CD40L is produced in Escherichia coli.
CD40L is used to induce its cognate signalling pathway in HEK-Blue™ CD40L Cell.
Working Concentration: 5 ng – 1 μg/ml
Biological activity: CD40L is biologically active when compared to a standard. The ED50, as determined by the dose-dependent stimulation of IL-12 and IL-8 induction by periphereal mononuclear cells was found to be <10 ng/ml.
Endotoxin: Less than 1 EU/mg of CD40L as determined by the LAL method
Formulation: CD40L was lyophilized from a PBS solution pH 7.0
Solubility: 100 μg/ml in water
