产品描述纤维蛋白原(Fibrinogen,Fg),即凝血因子I,分子量约340kDa,由α、β、γ三对不同多肽链组成,多肽链间以二硫键相连。α链分子量63.5kDa,β链分子量56kDa,γ链分子量47kDa,纤维蛋白原约含4%碳水化合物。纤维蛋白原参与凝血的原理:在凝血酶作用下,α链与β链分别释放出A肽与B肽,生成纤维蛋白单体。在此过程中,由于释放了酸性多肽,负电性降低,单体易于聚合成纤维蛋白多聚体,但此时单体之间借氢键与疏水键相连,尚可溶于稀酸和尿素溶液中。进一步在Ca2+与活化的ⅩⅢ因子作用下,单体之间以共价键相连,则变成稳定的不溶性纤维蛋白凝块,完成凝血过程。来源于不同物种(如来源于牛、猫、狗、豚鼠、人、绵羊、小鼠和大鼠等)的纤维蛋白原具有相似的结构和性质。因此,一般来源于一种哺乳动物的纤维蛋白原可与其他来源的凝血酶交叉反应,相反地来自一种哺乳动物蛋白的凝血酶液也可注入多种动物,发生凝血反应。泛素是一种小分子蛋白,存在于真核生物中,它在细胞内起到调节蛋白质降解、信号转导、细胞周期控制。Recombinant Human LIF R/CD118 Protein,His Tag
