Mouse TNF-alpha ELISA Kit - Quantikine HFD-induced plasma saturated free fatty acid (FFA) and lactate trigger production of proinflammatory cytokines and VEGF in mouse chondrocytes.(a~d) Relative mRNA levels of IL-6 (a), TNF-alpha (b), IL-1 beta (c) and VEGF (d) in the mouse primary chondrocytes treated with full or fractionated (>3 KD or <3 KD) serum from the 8-week ND or HFD-feeding mice. (n = 3, *P < 0.05, **P < 0.01 and ***P < 0.005). (e~h) Relative mRNA levels of IL-6 (e), TNF-alpha (f), IL-1 beta (g) and VEGF (h) in the mouse primary chondrocytes treated with BSA (5%) or BSA-linked FFA (18:0, 200 μM) for 24 h. (n = 3, *P < 0.05 and **P < 0.01). (i~l) Relative mRNA expression of IL-6 (i), TNF-alpha (j), IL-1 beta (k) and VEGF (l) in the mouse primary chondrocytes treated with lactate (25 mM) or vehicle control for 24 h. (n = 3, *P < 0.05 and **P < 0.01). Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/26271607), licensed under a CC-BY license.

Detection of Mouse Mouse TNF-alpha Quantikine ELISA Kit by ELISA PYC suppressed LPS-induced proinflammatory cytokine production in BV2 microglia.Cells were incubated with the indicated concentrations of PYC or vehicle for 1h before LPS treatment (500ng/mL). After 24 h incubation, the culture supernatants were collected, and the amount of TNF-alpha, IL-6, IL-1 beta and IL-10 were measured by ELISA (A-D). Data are represented as mean ± SD from at least 3 independent experiments. *P< 0.05 compared with LPS alone. #P< 0.05. Image collected and cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/26367267), licensed under a CC-BY license. Not internally tested by R&D Systems.

Preparation and Storage
Background: TNF-alpha
Tumor necrosis factor alpha (TNF-alpha ), also known as cachectin and TNFSF1A, is the prototypic ligand of the TNF superfamily (1). It is a pleiotropic molecule that plays a central role in inflammation, immune system development, apoptosis, and lipid metabolism (2-5). TNF-alpha is also involved in a number of pathological conditions including asthma, Crohn's disease, rheumatoid arthritis, neuropathic pain, obesity, type 2 diabetes, septic shock, autoimmunity, and cancer (5-11).
