Product Focus: TNF alpha antibody (70R-13763)


Scientific studies identifying TNF alpha involvement in the pathogenesis of Alzheimer’ disease has been a heavy focus of interest in the last 10 years. In vitro, with use of a human monocytic cell line, beta amyloid was found to stimulate secretion of TNF alpha [1].

TNF alpha in conjunction with interferon gamma was shown to induce A-beta production [2]. In addition, A-beta was shown to stimulate microglial inflammatory pathways, resulting in neurotoxicity mediated by TNF alpha generated by reactive microglia and monocytes [3].

Fitzgerald Industries International has over 50 TNF alpha antibodies, with one of their most popular being their affinity purified rabbit anti-TNF alpha due to its specificity and sensitivity in IHC and for its keen price. It has been validated for detection of Human, Mouse and Rat TNF alpha protein in Western Blotting and in IHC-P.
