TNF-beta/TNFSF1 Protein, Human (144a.a, HEK293, hFc)
TNF-β protein acts as a homotrimeric cytokine that binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR, and TNFRSF14/HVEM. TNF-beta/TNFSF1 Protein, Human (144a.a, HEK293, hFc) is the recombinant human-derived TNF-beta/TNFSF1 protein, expressed by HEK293, with N-hFc labeled tag.
- Species: Human
- Source: HEK293

Description
TNF-β protein acts as a homotrimeric cytokine that binds to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR, and TNFRSF14/HVEM. TNF-beta/TNFSF1 Protein, Human (144a.a, HEK293, hFc) is the recombinant human-derived TNF-beta/TNFSF1 protein, expressed by HEK293, with N-hFc labeled tag.
Background
TNF-beta Protein, in its homotrimeric configuration, exhibits binding capabilities to TNFRSF1A/TNFR1, TNFRSF1B/TNFBR, and TNFRSF14/HVEM, as demonstrated by various studies. Additionally, in its heterotrimeric association with LTB, it forms interactions with TNFRSF3/LTBR, underscoring its diverse receptor engagement. This cytokine, primarily produced by lymphocytes, showcases cytotoxic effects against a broad array of tumor cells both in vitro and in vivo. Structurally, TNF-beta exists as both homotrimers and heterotrimers, the latter comprising either two LTB and one LTA subunits or, to a lesser extent, two LTA and one LTB subunits. Furthermore, TNF-beta engages in interactions with TNFRSF14, emphasizing its pivotal role in mediating intricate immunological responses.

Product Properties
Lyophilized powder.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
