Product Overview
Clone HH-18 is a rabbit monoclonal antibody that recognizes transcription factor p65 (gene RELA) in human and mouse samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 60.2 kDa, and the supplier reports an observed band at about 65 kDa.
RelA (p65) is the main transactivating subunit of the classical NF-κB transcription factor, most often paired with p50. Inactive NF-κB is held in the cytoplasm by IκB; stimuli such as TNF, IL-1 and microbial products trigger IκB degradation, allowing p65 to enter the nucleus and switch on inflammatory, immune and survival genes. p65 phosphorylation and nuclear translocation are standard readouts of NF-κB activation.

Samples with confirmed staining (IHC): human transitional cells carcinoma of bladder tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Immunogen
Synthetic peptide based on the sequence of human NF-κB p65.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places transcription factor p65 in the nucleus and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
