01General information
- Description
NCI-H929 细胞系是一种人类骨髓瘤细胞系,来源于多发性骨髓瘤患者的骨髓。这些细胞能产生大量免疫球蛋白,因此在癌症研究中特别有用,是研究多发性骨髓瘤生物学和免疫球蛋白产生机制的最佳模型。NCI-H929 细胞以悬浮培养方式生长,倍增时间约为 40 小时,因此相对容易在实验室条件下繁殖。
从遗传学角度看,NCI-H929 细胞表现出与多发性骨髓瘤常见的几种染色体异常,包括易位和扩增。这些遗传特征使它们成为研究骨髓瘤遗传基础和测试潜在治疗干预措施的宝贵资源。研究人员经常利用 NCI-H929 细胞进行药物筛选试验,以评估新型抗骨髓瘤化合物的疗效并了解耐药机制。在各种实验条件下,NCI-H929 细胞的行为具有一致性和可重复性,这进一步增强了它们在临床前研究中的作用。

05Handling and culture
- Culture medium
- RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
- Incubation atmosphere
37°C, 5%CO2, 加湿环境。
- Supplements
- 在培养基中添加 10% FBS
- Subculturing
- 悬浮细胞:用新鲜培养基移取基质中的细胞。要获得单细胞,可将悬浮液通过 22 号针头数次,然后分装到新的烧瓶中。
- 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.
06Quality 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。

08Legal 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。
