Product Overview
This rabbit polyclonal antibody recognizes tumor necrosis factor receptor superfamily member 1A (gene TNFRSF1A) in human, mouse and rat samples and is validated for flow cytometry, ICC/IF and Western blot. The predicted molecular weight is 50.5 kDa, and the supplier reports an observed band at about 55–60 kDa.
TNFR1 (TNFRSF1A, p55) is the main signaling receptor for TNF and is expressed on nearly all cell types. It recruits TRADD, RIPK1 and TRAF2 to activate NF-κB and MAP kinases, or, under other conditions, forms a caspase-8-containing complex that triggers apoptosis or necroptosis. Mutations in TNFRSF1A cause TNF receptor–associated periodic syndrome (TRAPS).

Immunogen
Recombinant human TNFRSF1A fragment (Phe89–Asn145), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 67.3% and 69.1%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes tumor necrosis factor receptor superfamily member 1A as secreted and also located in the cell membrane and Golgi apparatus membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
