该细胞来源于一名15岁的白人少年的肝癌组织。该细胞表达甲胎蛋白、白蛋白、α-2-巨球蛋白、α-1-抗胰蛋白酶、转铁蛋白、α-1-抗凝乳蛋白酶、结合珠蛋白、铜蓝蛋白、纤溶酶原、补体C4、C3激活物、纤维蛋白原、α-1酸性糖蛋白、α-2-HS-糖蛋白、β-脂蛋白、视黄醇结合蛋白;表达胰岛素受体和胰岛素样生长因子IGFⅡ的受体;该细胞具有3-羟基-3-甲酰辅酶A还原酶和肝甘油三酯脂肪酶的活性。目前尚未证明该细胞中有HBV基因组。
所供Luciferase 稳转细胞株采用慢病毒法构建,除稳定高效地表达 luciferase 基因外,还具有特异性强、成像质量高、发光强度可精确定量等优点,可实现包括启动子活性研究、哺乳动物细胞双杂交实验以及活体动物成像实验等多方面的灵活应用。
基因报告系统广泛应用于真核生物基因表达和细胞生理学的研究,是提高实验准确度的常用方法。荧光素酶(Luciferase)是以荧光素(luciferin)或脂肪醛(firefly aldehyde)为底物来检测荧光素酶活性的一种常见基因报告系统,因其具有方便快捷、灵敏度强、成功率高等优点,在基因表达的研究中得到广泛应用。

HepG2细胞培养要点
1. HepG2细胞的生长特点就是呈岛状生长,并且岛状生长的细胞扩张能力有限,长到一定大小之后就会堆积生长。
2. 要想细胞分散均匀,一方面是需要保证细胞消化过程中分散良好,另外一方面接种的初始密度不宜过低,否则就会有大面积的空白区域。
3. 另外如果实验需要Hep G2为分散良好的单层细胞,可以用多聚赖氨酸包被培养瓶后培养,细胞将会呈单层分散的形式生长,但是形态跟不包被时差异比较大,会变成长梭形细胞。
