Tumor Necrosis Factor-alpha (TNF-alpha), Mouse

Tumor necrosis factor alpha (TNF-alpha) is produced by neutrophils, activated lymphocytes, macrophages, NK cells, LAK cells, astrocytes endothelial cells, smooth muscle cells and some transformed cells. Mouse TNF-alpha occurs as a membrane-anchored form. The naturally-occurring form of TNF-alpha is glycosylated, but non-glycosylated recombinant TNF-alpha has comparable biological activity. The biologically active native form of TNF-alpha is reportedly a trimer. Human and mouse TNF-alpha show approximately 79% homology at the amino acid level and crossreactivity between the two species.

Lyophilized from a 0.2um filtered solution in PBS, pH 7.2.

This lyophilized preparation is stable at 2-8 C, but should be kept at -20 C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 C to -70 C. Avoid repeated freeze/thaw cycles.
