产品简介
碱性成纤维细胞生长因子(bFGF)是成纤维细胞生长因子(FGF)家族的成员,是由FGF2基因编码的生长因子和信号蛋白。FGF家族成员具有广泛的促有丝分裂和细胞存活活性,并参与多种生物学过程,包括胚胎发育、细胞生长、形态发生、组织修复、肿瘤生长和侵袭。在正常组织中,bFGF存在于基底膜和血管内皮下细胞外基质中。bFGF能刺激和调节血管内皮细胞、上皮细胞、成肌细胞、成骨细胞和神经胶质细胞等多种起源于中胚层、神经外胚层的细胞分化增殖,在胚胎发育、组织愈合中起重要作用。bFGF/FGF-2,是所有胚胎和诱导多能干细胞培养基中维持多能性的基本成分。
本品由大肠杆菌表达,以液体形式提供,高活性、高纯度、低内毒素、无标签。
