Anti-NFkB-p65 (K303) Antibody

This polyclonal reagent from Antibodies.com targets the NFkB-p65 (RelA) subunit of the NF-κB transcription factor family, with specificity directed at the lysine residue at position 303. Raised in rabbit, the antibody is unconjugated and supplied at 1 mg/ml in phosphate buffered saline (PBS) containing 0.05% sodium azide at approximately pH 7.2, packaged in a 50 µl vial.

Validated for Western blot, immunohistochemistry, and immunofluorescence workflows, the reagent shows reactivity against human, mouse, and rat samples. K303 sits within a region of RelA subject to post-translational regulation, and the antibody is well suited to studies of NF-κB signaling in inflammation, immune activation, and cellular stress responses where site-specific probing of the p65 subunit is required.

For handling, refrigerate the vial upon arrival; aliquot and freeze for long-term storage, and minimize freeze-thaw cycles to preserve antibody activity.
