Synchronization of HeLa Cells

HeLa is one of the oldest and most commonly used cell lines in biomedical research. Owing to the ease of which they can be effectively synchronized by various methods, HeLa cells have been used extensively for studies of the cell cycle

Preparation of HeLa Nuclear Extracts

Promoter-specific in vitro transcription by RNA polymerase II is now achievable with cell extracts prepared from a variety of animal and plant sources (1 –3 ). For extracts prepared from mammalian cells, HeLa cells provide many advantages

海拉细胞 HeLa cell

　　1951年由 G． O． Gey等从人子宫颈癌组织分离出来的株细胞。 HeLa是原患者姓氏的缩写。这种细胞是现有来自人体的组织培养中最早的分离细胞，在世界各地的研究室继续培养，广泛应用于各种研究。它们在体外容易增殖形成上皮性的细胞排列。染色体数频率分布式为 78— 80，移植于人体皮下则形成肿瘤，在豚鼠的眼前房，大鼠的颊囊以及经 X射线皮质酮处理的小鼠可作异种移植，由此可以认为仍保持着癌的性状。广泛被用作分析细胞营养要求、细胞增殖和各种细胞化学的研究材料。易从细胞群落作无性
