It plays a central role in physiological and pathological processes including inflammation, immune regulation, and apoptosis. As a pro-inflammatory cytokine, TNF-α participates in normal inflammatory and immune responses. It orchestrates tissue homeostasis by coordinately regulating the production of other cytokines, as well as modulating cell survival and death. TNF-α exerts diverse functions in various developmental and immune processes—such as inflammation, differentiation, lipid metabolism, and apoptosis—and is implicated in numerous diseases.\u003c\/p\u003e\u003c\/div\u003e\n\u003ch2 style=\"color: #0056b3; border-bottom: 2px solid #0056b3; padding-bottom: 8px; margin-top: 30px; font-size: 22px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"biofargo-table-wrapper\"\u003e\u003ctable class=\"biofargo-spec-table\"\u003e\n\u003cthead\u003e\u003ctr style=\"background-color: #0056b3; color: white;\"\u003e\u003cth style=\"padding: 12px; text-align: left;\" colspan=\"2\"\u003eProduct Details\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"font-weight: bold; background-color: #f8f9fa;\" width=\"26%\"\u003eCat.
