01General information
- Description
HEK293-F 细胞是从人类胚胎肾脏 293(HEK293)细胞系中提取的一种快速生长、高度可转染的亚系。F "表示这些细胞适合在悬浮培养物中生长,因此特别适用于大规模蛋白质生产。这些细胞在各种无血清培养基中生长,有利于生物技术和制药应用中的可扩展过程。HEK293-F 细胞保留了母系 HEK293 的上皮样形态,可悬浮培养,无需附着在固体基质上。
这些细胞能高效表达重组蛋白,被广泛用于生产用于基因治疗的病毒载体,包括腺病毒、慢病毒和逆转录病毒载体。它们在悬浮液中生长旺盛,易于转染,因此非常适合用于瞬时转染方案,可在转染后几天内生产出高产蛋白。这一特性对于研究和工业环境中的快速生产周期至关重要。HEK293-F 细胞对各种生长条件的适应性及其高密度培养的能力提高了它们在生物加工环境中的实用性。

- Subculturing
- 去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。

- Post-thaw recovery
- 解冻后,将细胞以5×10⁴个细胞/平方厘米的密度接种于培养皿中,使细胞从冷冻过程中恢复并至少贴壁24小时。
- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.
For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.
Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
07Quality control and cryopreservation
- Sterility
使用基于 PCR 的检测方法和基于发光的支原体检测方法排除支原体污染。
为确保没有细菌、真菌或酵母菌污染,每天都要对细胞培养物进行目视检查。
- Freeze medium
- 我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
- Storage conditions
如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。
- Shipping conditions
冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。

09Legal and safety
- Safety precautions
- 计划将低温样品储存在液氮中以便将来解冻时,必须遵守严格的安全措施。在将冷冻样本移入或移出液氮罐时,必须穿戴适当的防护手套和防护服,并使用面罩或安全护目镜。这样做是为了降低在移出时因冷冻样品爆炸而造成伤害的风险,因为爆炸可能导致锋利的碎片飞溅。
