Anti-CD39 Antibody

Raised in rabbit as a polyclonal reagent, this unconjugated primary antibody from Antibodies.com is directed against CD39 (ENTPD1) and is supplied as a 50 µL liquid formulation at 1 mg/mL in PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide. The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using an epitope-specific immunogen derived from a synthesized peptide mapping to the internal region of human CD39, and it detects endogenous levels of the target protein. It is validated for Western blot (WB) and ELISA applications and has been tested for reactivity against human, mouse, and rat samples, making it a broadly useful reagent across commonly studied mammalian model systems. The product is dispatched from Cambridge (UK) with a typical lead time of 6–9 business days and is intended for research use only, not for diagnostic or therapeutic applications. Store refrigerated (typically 2–8 °C short term or –20 °C for longer-term aliquots) according to standard laboratory practice for glycerol-containing antibody preparations. For laboratories working on purinergic signaling, immune cell ectoenzymes, or tumor-microenvironment studies where CD39 expression is a key biomarker, this lot offers a reliable, well-characterized option from a trusted catalog supplier.
