Proteintech Group Inc Human TNFR1 ELISA Kit 96well
Supplier: Proteintech Group Inc KE0005196T
Tumor necrosis factor (TNF) is a multifunctional cytokine that plays a key role in regulating inflammation, immune functions, host defense, and apoptosis. TNF signals through two distinct cell surface receptors, TNFR1 (TNFRSF1A, CD120a) and TNFR2 (TNFRSF1B, CD120b). TNFR1, which contains a death domain (DD) within its intracytoplasmic region, is thought to be the key receptor for TNF signaling. This receptor can be released to the extracellular space by two mechanisms, ectodomain shedding and constitutive release of full-length 55-kDa TNFR1. Soluble TNFR1 (sTNFR1) could function as TNF-binding protein, inhibiting TNF bioactivity. This ELISA kit can be used to measure natural and recombinant human sTNFR1.
