Recombinant Human CD40 Ligand/TNFSF5 Protein, hFc & AVI Tag, Biotinylated
Recombinant Human CD40 Ligand/TNFSF5 Protein, hFc & AVI Tag, Biotinylated is engineered for site‑specific biotinylation while retaining CD40 engagement. Used in B‑cell organoids and immune co‑cultures to quantify CD40‑mediated activation and antibody production. Fc fusion provides stability, and biotinylation supports high‑sensitivity assays. Produced with stringent QC for reproducible immune modeling.
