Product Overview
Clone AAIB-20 is a rabbit monoclonal antibody that recognizes tumor necrosis factor receptor superfamily member 1B (gene TNFRSF1B) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 48.3 kDa, and the supplier reports an observed band at about 65 kDa.
TNFR2 (TNFRSF1B, p75) is the second receptor for TNF, found mainly on immune cells, endothelial cells and neurons. It lacks a death domain and signals through TRAF2 to activate NF-κB, promoting cell survival and proliferation. TNFR2 is highly expressed on regulatory T cells and is studied in immune regulation, inflammation and cancer.

Samples with a confirmed band (WB): human THP-1 cells, human K562 cells, human Caco-2 cells, human RT4 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): rat spleen tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human TNF Receptor II.
Reactivity Notes
