CD40–CD40L interaction drives B cell activation, germinal center formation, and isotype switching, making precise characterization of this axis essential for immunology and therapeutic antibody development. This recombinant human CD40 construct spans the extracellular ligand-binding domain (aa 21–193) with a C-terminal hFc tag, and LSPR analysis confirms a KD of 2.06 nM against CD40L, demonstrating conformational integrity that supports SPR/BLI affinity characterization, blocking antibody screening, and epitope mapping studies. Functional ELISA further validates ligand engagement, with an EC50 of 3.112–3.858 ng/mL when binding CD40L, providing a reliable positive control for receptor-ligand interaction assays and small-molecule inhibitor screening. Mammalian cell expression preserves native glycosylation and folding, while purity exceeding 90% by SDS-PAGE and endotoxin levels below 1.0 EU/μg satisfy criteria typical for cell-based functional assays and drug discovery workflows.
