細胞激素(Cytokines)-Human TNF-α protein重組蛋白

細胞激素（Cytokine , CK）是由免疫細胞（如單核細胞、巨噬細胞、T細胞、B細胞、NK細胞等）和一些非免疫細胞合成和分泌的一類具有廣泛生物活性的小分子多肽或糖蛋白。內皮細胞、表皮細胞、纖維母細胞等）受到刺激後。細胞激素可以介導細胞間的相互作用，具有多種生物學功能，如調節細胞生長、分化和成熟、功能維持、調節免疫反應、參與發炎、傷口癒合和腫瘤生長和衰退等。細胞激素(Cytokines)是一類獨特的細胞訊號傳導分子，在細胞增殖和發育中扮演重要角色。Abbkine 提供細胞因子，包括白血球介素( interleukin)、趨化因子(chemokines)、集落刺激因子(colony-stimulating factors, CSF)、干擾素(interferon)以及轉化生長因子(transforming growth factor , TGF) 和腫瘤壞死因子(tumor necrosis factor , TNF) 家族，用於癌症(cancer)、細胞凋亡(apoptosis)、內分泌學(endocrinology)、免疫學(immunology)、神經科學(neuroscience)、蛋白酶(proteases)、和幹細胞研究。這些細胞激素經過全程品質管制，品質嚴格驗證，可以滿足科學家對高品質、純度高、內毒素含量低、高生物活性和有競爭力的價格的需求。 由非動物原料和表現系統生產，其中培養基不含血清、動物成分且化學成分明確。以 LAL 方法測定，每 μg 蛋白質 <1 EU。<1 EU per μg of the protein as determined by the LAL method.

Human TNF-α protein重組蛋白|貨號PRP1013

腫瘤壞死因子α（TNF-α）又稱TNF、TNFA或TNFSF2，是TNF超家族的原型細胞因子，是一種多功能分子(multifunctional molecule)，參與調節多種生物過程，包括細胞增殖( cell proliferation)、分化、細胞凋亡(differentiation)、脂質代謝(apoptosis)和凝血( coagulation)。兩種受體 TNF-R1（TNF 受體 1 型；CD120a；p55/60）和 TNF-R2（TNF 受體 2 型；CD120b；p75/80）與 TNF-α 結合。 TNF-α 蛋白主要由巨噬細胞產生，脂多醣、其他細菌產物和白介素-1 (IL-1) 會釋放大量這種細胞激素。 TNF-α參與對抗腫瘤發生(tumorigenesis)，因此被視為癌症治療的分子洞察力。

產品介紹: 人類TNF-α蛋白，序列 表達源自人類TNF-α。可溶形式(NP_000585.2)(Val 77-Leu 233)的胺基酸序列，在N端具有初始Met。活性 在代謝抑制劑放線菌素 D 存在的情況下，使用 L929 小鼠纖維肉瘤細胞進行細胞毒性測定。此效應的 ED50 通常為 25-100 pg/ml。蛋白質長度 重組人類 TNF-α 由 161 個胺基酸組成，預測分子量為 17.7 kDa，這也是透過 SDS-PAGE 估算的。製備方法 大腸桿菌。SDS-PAGE 測定純度 > 95 % 。收到貨品打開前務必先離心管。建議以 12,000 rpm 離心 1 分鐘。建議使用我們提供的不少於100 µg/mL的緩衝液，重建冷凍乾燥FGF21蛋白，然後可以進一步稀釋到其他水溶液中。

FGF21 是纖維母細胞生長因子 (FGF) 家族的成員。此家族的蛋白具有廣泛的促有絲分裂和細胞存活活性，參與多種生物過程，如血管生成、傷口癒合、神經發育、腫瘤發生和發展等。大多數 FGF（FGF3-8、10、15、17-19、21-23）在 N 端具有典型的訊號序列分泌蛋白。其中，纖維母細胞生長因子21（FGF 21）在肝臟中特異性表達，透過脂肪組織和胰臟範圍降低血糖和三酸甘油酯。胰高血糖素可改善胰島 B 細胞的功能，進而預防飲食引起的肥胖和胰島素抗性。此外，FGF21也被證明是一種主要的血清素內源性調節因子，在禁食和酮症中發揮關鍵作用。

Annexin V是一種鈣離子依賴性磷脂結合蛋白，分子量為35~36KDa，能以高親和力與磷脂醯絲胺酸PS特異性結合。在正常細胞中，磷脂醯絲胺酸僅分佈在細胞膜脂質雙層的內側。在細胞凋亡的早期，膜上的磷脂醯絲胺酸（PS）從脂膜的內側轉向外側。作為一種磷脂結合蛋白，Annexin V 與磷脂醯絲胺酸具有高親和力。它透過暴露在細胞外部的磷脂酰絲氨酸與細胞凋亡早期的細胞膜結合。因此，Annexin V是檢測早期細胞凋亡的敏感指標。

腫瘤壞死因子配體超家族成員11，又稱為核因子受體活化劑kappa-B配體、骨保護素配體、TNFSF11、RANKL、TRANCE、OPGL和CD254，在多種細胞中表達，包括成骨細胞、纖維母細胞、活化的T細胞和骨髓基質細胞可以與誘餌受體 OPG 相互作用。TNFSF11參與許多基本生物學過程，例如調節T細胞和樹突狀細胞之間的相互作用、調節T細胞依賴性免疫反應以及增強惡性腫瘤體液高鈣血症中的骨吸收。TNFSF11也增強了樹突細胞刺激初始T細胞增生的能力。
