The TNFR1-B1 antibody reacts with the extracellular domain of CD120A which is also known as the 55 kDa receptor for the human cytokines, tumor necrosis factor (TNF) and lymphotoxin-alpha (LT-α). This receptor is referred to as the p55 or Type I Tumor Necrosis Factor Receptor (TNFRI). TNFRI are expressed by a variety of cell lines, tumor cells, and normal cell types including T cells, monocytes, macrophages, neutrophils, endothelial cells, hepatocytes, chondrocytes, and fibroblasts. Naive B cells express very low or undetectable levels of TNFRI whereas mature erythrocytes and platelets are uniformly negative for TNFRI expression. For the generation of the MABTNFR1-B1 hybridoma, BALB/c mice were immunized with purified, full-length human TNFRI protein that was expressed by insect cells that were infected with a recombinant human TNFRI-baculovirus expression vector. MABTNFR1-B1 specifically binds to natural and recombinant truncated forms of TNFRI. Expression of cell surface TNFRI by non-activated human PBMC or RBC. Human PBMC (left panel) and red blood cells (right panel) isolated by density centrifugation (Ficoll-Paque™) were stained with MABTNFR1-B1 (0.5 μg, Cat No. 550514) followed by biotinylated goat anti-mouse Ig (0.25 μg, Cat . No. 553999) and Streptavidin Phycoerythrin (0.015 μg, Cat. No. 554061) in a three-step staining protocol to amplify immunofluorescent signals. Staining with the MABTNFR1-B1 antibody (filled histograms) is compared to staining obtained using the secondary antibody alone (open histograms). Histograms in the left panel are gated on the lymphocyte population. Note: Certain human cell lines or cell types (e.g., neutrophils, monocytes) can first be treated with reagents that block receptors for the Fc regions of immunoglobulin to avoid nonspecific immunofluorescent staining mediated by Fc receptors.
