Anti-TNF alpha Antibody [B1E4]

A mouse monoclonal IgG1 antibody from Antibodies.com, clone B1E4, targets human Tumor Necrosis Factor alpha for detection in ELISA and Western Blot workflows.

Supplied as a lyophilised powder in a single vial containing 500 µg of antibody, this unconjugated primary reagent binds the pro-inflammatory cytokine and is reactive with human samples. Researchers investigating cytokine signalling in inflammation, autoimmune disease models such as rheumatoid arthritis, inflammatory bowel disease, and sepsis pathways use this reagent to profile endogenous TNF alpha expression in cell culture supernatants and tissue lysates.

The lyophilised format supports long-term storage stability, and the antibody is reconstituted in sterile buffer prior to immunoassay use. Intended for research use only, it supports laboratory studies of NF-kB activation, macrophage activity, and the broader inflammatory cascade driven by this cytokine.
