TNF-ALPHA MOUSE RECOMBINANT E. COLI (C15-1307-369)

General description

Recombinant, mouse tumor necrosis factor-α expressed in E. coli. Has the ability to kill certain tumor cells directly. It is referred to as an inflammatory cytokine as it initiates the cascade of other cytokines and factors that make up the immune system′s response to infection and cancer. Reported to mediate changes in bone metabolism during inflammation.
