Recombinant Human CD40 Ligand/TNFSF5 Protein, hFc Tag
Recombinant Human CD40 Ligand/TNFSF5 Protein, hFc Tag is a trimeric immune co‑stimulatory molecule that activates CD40 on B cells, dendritic cells, and macrophages. In organoid systems, it is applied to immune and tumor co‑cultures to study antigen presentation, B‑cell activation, and tumor–immune interactions. Fc fusion enhances stability and avidity, while HPLC QC ensures purity and reproducibility.
