Anti-CD137L Antibody

Affinity-purified polyclonal reagent raised in Rabbit against the human CD137L immunogen, supplied by Antibodies.com as an unconjugated preparation in 100 µl format. Validated applications include western blot, immunofluorescence, and ELISA workflows.

CD137L (also designated 4-1BBL and TNFSF9) is a type II transmembrane glycoprotein of the TNF ligand superfamily expressed on activated antigen-presenting cells, where it engages the receptor CD137 to deliver co-stimulatory signals that drive CD8+ T cell proliferation, cytokine production, and memory formation. The antibody specifically detects the human target, supporting studies of T cell co-stimulation, immune checkpoint signaling, and tumor immunology research on cultured cells and tissue sections.

The unconjugated format allows flexible pairing with user-selected secondary reagents for chromogenic or fluorescence-based detection. Store refrigerated and protect from light to preserve reagent activity across multiple freeze-thaw cycles when aliquoted for working stocks.
