CD40L / CD154 recombinant protein

Cat No. GTX65048

Application ELISA, Functional Assay, Apuri, Blocking
Reactivity Human
Species Human

Application Note

Protein's bioactivity determined by the stimulation of IL-12 induction by human peripheral blood mononuclear cells (PBMC) and the stimulation of IL-8 induction by human PBMC. The expected ED50 for this effect is 5-10 ng/ml. Note: results may vary with PBMC donors.

Calculated MW

16.3 kDa. ( Note )


Lyophilized powder


10 mM Sodium Phosphate, pH 7.5


Reconstitute in 5-10 mM Sodium Phosphate (pH 7.5) to a concentration of 0.1-1.0 mg/ml. The solution can then be diluted into other aqueous buffers or stored at 4ºC for 1 week or –20ºC for future use
