4-1BB Ligand Recombinant Protein

Biological activity was determined by the dose - dependent stimulation of IL - 8 production by human PBMC. The ED50 for this effect is 5 - 10 ng/mL. Please Note: Results may vary with PBMC donors.

The lyophilized 4-1BB Ligand recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted 4-1BB Ligand is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing 4-1BB Ligand recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
