General description
纤连蛋白(Fibronectin)是一种高分子质量粘合糖蛋白,主要存在于细胞外基质(ECM),广泛分布于组织和血液中。FN基因高度保守,在人体中通过选择性剪接产生20种以上亚单位。比较有名的有细胞FN和血浆FN。血浆FN主要在肝脏中合成,细胞FN仅占循环纤连蛋白的5%,由各种细胞局部表达。
Biochem/physiol Actions
纤连蛋白在生物过程中起重要作用。可作用于表面受体和其他主要ECM蛋白(如胶原蛋白)介导细胞信号转导。纤连蛋白参与多种细胞功能,包括细胞粘附、细胞骨架组织、致癌性转化、细胞迁移、吞噬、止血和胚胎分化。这种糖蛋白可结合整合素、胶原蛋白、纤维蛋白和糖胺聚糖(GAG)。纤连蛋白在促进细胞周期进展和增殖中起重要作用。这种作用影响周期蛋白和即刻早期反应基因,与细胞分裂和生长相关过程有关。纤连蛋白也参与多种细胞的生存和抗凋亡保护,包括上皮细胞、内皮细胞和白细胞。在这些细胞中,FN是促进细胞生存和防止程序性细胞死亡的关键因子。FN基因突变与FN肾小球病和脊柱干骺端发育不良症有关。纤连蛋白在创伤愈合与细胞外基质(ECM)组装中起重要作用,适合组织工程应用。
Preparation Note
本品从 0.05 MTris 缓冲盐水 (pH 7.5) 冻干。溶于水 (1 mg/mL) , 在 37°C 至少溶解 30 min。可能残留少量未溶解物质,但不会影响性能。通过免疫电泳评价蛋白的均一性,检测内毒素,并且检测源材料的 HIV、乙型肝炎和丙型肝炎呈阴性。
在包被培养表面,纤维连接蛋白应在无菌平衡无菌盐溶液中稀释,并以最小体积包被。表面应在室温下风干 45 min,并可在 2-8℃ 下储存 2-4 周。
