Description
CD40 ligand drives critical costimulatory signaling through CD40 on antigen-presenting cells, activating NF-κB and MAPK pathways central to B-cell proliferation, differentiation, and anti-tumor immune responses. This recombinant human CD40LG (residues 113–261) carries an N-terminal hFc-Flag tag and demonstrates strong binding activity in functional ELISA, with an EC50 of 2.353–3.232 ng/ml against an anti-CD40L monoclonal antibody, confirming its suitability as a coating antigen for antibody validation, an ELISA positive control, or a reference standard in CD40L detection assays. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, supporting use in B-cell activation and proliferation assays, NF-κB signaling studies, and in vivo tumor immunology models where spurious innate immune stimulation would confound results. Purity exceeding 90% by SDS-PAGE, combined with this stringent endotoxin control, aligns with standards expected in cell-based functional assays and antibody development workflows.
