CD120a is a 55 kD Type I transmembrane protein, also known as Tumor Necrosis Factor Receptor Type I (TNFRI) or p55. It is expressed on a variety of cells at low levels. Resting T cells and erythrocytes express very little to no CD120a. This receptor binds both TNF-α and LT-α (also known as TNF-β). In association with TRADD and RIP, the receptor crosslinking induced by TNF-α or LT-α trimers is critical for signal transduction, leading to apoptosis, NF-kB activation, increased expression of proinflammatory genes, tumor necrosis, and cell differentiation depending on cell type and differentiation state. The 55R-170 antibody has been shown to block in vitro and in vivo receptor signaling initiated by ligand binding.Product Details

FC - Quality tested
ELISA Detection - Reported in the literature
- Recommended Usage
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
Flow Cytometry: For the most successful immunofluorescent staining results, it may be necessary to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated antibody (Cat. No. 112904) or biotinylated anti-Armenian hamster IgG (Cat. No. 405501) second step, followed by SAv-PE (Cat. No. 405204)).
ELISA Detection1: The biotinylated 55R-170 antibody is useful as a detection antibody when paired with the purified 55R-286 antibody (Cat. No. 113002) as the capture antibody.
Additional reported applications (for the relevant formats) include:immunoprecipitation1, and In vitro and In vivo receptor blocking1. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for functional assays (Cat. No. 112902).
