Anti-NFkB-p105 / p50 (Ab-337) Antibody

This polyclonal reagent from Antibodies.com targets the Ab-337 epitope region of NF-κB p105/p50, a transcription factor subunit implicated in inflammatory signaling, immune cell activation, and cellular stress responses. The antibody recognizes both the full-length p105 precursor and its processed p50 form, allowing researchers to track NF-κB pathway activation in cell lysates and tissue sections. Validated for Western blot and immunohistochemistry, with confirmed reactivity against human, mouse, and rat samples. The unconjugated rabbit polyclonal format enables flexible pairing with HRP-, biotin-, or fluorophore-conjugated secondary reagents for chromogenic or immunofluorescence detection. Supplied as a 100 µL aliquot of antiserum suitable for both chemiluminescent western workflows and standard IHC protocols on fixed tissue. Store aliquots at -20°C and avoid repeated freeze-thaw cycles to preserve binding activity.
