Anti-OX40L (human), clone R4930 (rec.) (blocking) (preservative free)

OX40L [CD252, CD134L] is a membrane-expressed cytokine that belongs to the TNF ligand family. It acts as costimulator through interaction with its ligand OX40 on T cells, stimulating T cell activation, proliferation and cytokine production. OX40L is expressed on antigen presenting cells including B cells, dendritic cells, mast cells and endothelium. Protein function: Cytokine that binds to TNFRSF4. Co-stimulates T-cell proliferation and cytokine production. [The UniProt Consortium]
