Recombinant protein corresponding to mouse TNFa, expressed in E. coli.
Tumor Necrosis Factor alpha (TNF-alpha) is a 17.3kD multi-functional pro-inflammatory cytokine primarily secreted by macrophages, but also produced by T and B lymphocytes, activated monocytes and fibroblasts. TNF-alpha exists in both a transmembrane and mature soluble form and has many biological properties, including activation of transcription factor NF-KappaB, the induction of apoptosis in various tumor cell lines and the stimulation of cell differentiation and proliferation under certain conditions. Studies have revealed a role for TNF-alpha in inflammation, septic shock, autoimmune disease and rheumatoid arthritis. Applications: Suitable for use in ELISA and Western Blot. Other applications have not been tested. Recommended Dilution: ELISA (Sandwich): 0.5-2ug/ml. (100ul/well) will detect at least 2000-4000pg/well of recombinant mouse TNFa when used with T9160-03D as the capture antibody. Western Blot: 0.1-0.2ug/ml. Detection limit is 1.5-3ng/lane, under either reducing or non-reducing conditions Optimal dilutions to be determined by the researcher.
