細胞激素(Cytokines)-Human CD24 重組蛋白，hFc 標籤（無動物源）

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.

The cluster of differentiation (CD) system is commonly used as cell markers in immunophenotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 32 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. Cluster of differentiation 24, also known as signal transducer CD24 or heat stable antigen CD24 (HSA), is a mucin-type glycosylphosphatidylinositol-linked glycoprotein expressed on the surface of B-cells, differentiating neuroblasts and many tumors. May have a pivotal role in cell differentiation of different cell types. Signaling could be triggered by the binding of a lectin-like ligand to the CD24 carbohydrates, and transduced by the release of second messengers derived from the GPI-anchor. Modulates B-cell activation responses. Promotes AG-dependent proliferation of B-cells, and prevents their terminal differentiation into antibody-forming cells. In association with SIGLEC10 may be involved in the selective suppression of the immune response to danger-associated molecular patterns (DAMPs) such as HMGB1, HSP70 and HSP90. Plays a role in the control of autoimmunity.

分化簇 (CD) 系統通常用作免疫表型分析中的細胞標記。免疫系統中不同種類的細胞可以透過表面的CD分子來識別，CD分子與細胞的免疫功能有關。已識別出超過 32 個 CD 獨特簇和子簇。一些 CD 分子透過啟動訊號級聯來充當對細胞重要的受體或配體，然後改變細胞的行為。有些CD蛋白不參與細胞訊號處理，但具有細胞黏附等其他功能。分化簇24，也稱為訊號傳導器CD24 或熱穩定抗原CD24 (HSA)，是一種表達於B 細胞表面的黏蛋白型糖基磷脂酰肌醇連接糖蛋白，可分化神經母細胞和許多腫瘤。可能在不同細胞類型的細胞分化中發揮關鍵作用。訊號傳導可以透過凝集素樣配體與 CD24 碳水化合物的結合來觸發，並透過 GPI 錨衍生的第二信使的釋放來進行轉導。調節 B 細胞活化反應。促進 B 細胞的 AG 依賴性增殖，並防止其終末分化為抗體形成細胞。與 SIGLEC10 相關可能參與選擇性抑制對危險相關分子模式 (DAMP)（例如 HMGB1、HSP70 和 HSP90）的免疫反應。在控制自體免疫方面發揮作用。

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。
