人细胞纤维连接蛋白
Fibronectin is a multi-domain glycoprotein composed of an array of multiple repeated modular structures. Cellular fibronectin, an adhesion glycoprotein of the extracellular matrix, exists as a dimer with a molecular mass of ~ 550 kDa. This structure is composed of two heterodimers, the A chain and the B chain containing the type III connecting segment region. Cellular fibronectin differs from plasma fibronectin by the presence of additional polypeptide segments and its capacity to specifically regulate morphology and growth of attached cells including stem cells [1, 2, 3, 4]. Multiple domains of fibronectin show binding affinities for collagen, fibrin, heparin, and specific cell membrane receptors such as integrins. Fibronectin matrix assembly is essential for normal development and contributes to the generation of tumor metastases.
ScienCellTM Human Cellular Fibronectin (HCF) is produced from human fibroblasts maintained in serum-free media and then purified biochemically. HCF is supplied sterile in CAPS saline buffer.

纤维连接蛋白(Fibronectin)是一种多结构域糖蛋白,由多个重复的模块化结构组成。细胞型纤维连接蛋白(Cellular Fibronectin)是细胞外基质中的一种黏附性糖蛋白,以二聚体形式存在,分子量约为 550 kDa。该结构由两条异源二聚链组成,即 A链和B链,其中包含 III型连接片段(Type III connecting segment) 区域。
与血浆型纤维连接蛋白(Plasma Fibronectin)相比,细胞型纤维连接蛋白含有额外的多肽片段,并且能够特异性调控贴壁细胞(包括干细胞)的形态和生长 [1,2,3,4]。纤维连接蛋白的多个结构域可与胶原蛋白、纤维蛋白、肝素以及整合素(integrins)等细胞膜受体结合。纤维连接蛋白基质的组装对于正常发育过程至关重要,同时也与肿瘤转移的形成有关。
ScienCell™ 人细胞纤维连接蛋白(Human Cellular Fibronectin,HCF)来源于在无血清培养基中培养的人成纤维细胞,并通过生化方法纯化获得。本产品以无菌 CAPS 盐缓冲液形式提供。
