01General information
- Description
RPMI 8226 细胞是一种人类骨髓瘤细胞系,于 1966 年从一名 61 岁的男性多发性骨髓瘤患者的外周血中建立。该细胞系以其研发地罗斯威尔帕克纪念研究所(RPMI)命名,8226 表示其在细胞库中的具体目录编号。
RPMI 8226 细胞系是研究多发性骨髓瘤以及浆细胞生物学、免疫学研究和癌症治疗相关方面的重要模型系统。众所周知,RPMI 8226 细胞能产生和分泌免疫球蛋白的 kappa 轻链,研究人员经常利用这一特性来调查抗体的产生和分泌机制。
RPMI 8226 细胞表现出许多染色体异常,这是多发性骨髓瘤细胞的典型特征。这些异常包括影响各种致癌基因和抑癌基因的易位、缺失和扩增。
人类骨髓瘤细胞系 RPMI 8226 被广泛用于药物发现和开发研究,并被用于研究耐药途径和评估联合疗法。
总之,RPMI 8226 细胞为多发性骨髓瘤研究提供了一个重要的体外模型,有助于研究这种疾病的生物学和分子机制以及开发治疗策略。

06Handling 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
- Dissociation reagent
- Accutase
- Subculturing
- 将悬浮细胞收集到 15 毫升试管中,用不含钙和镁的 PBS(T25 烧瓶用 3-5 毫升,T75 烧瓶用 5-10 毫升)轻轻清洗粘附的细胞。涂抹 Accutase(T25 烧瓶 1-2 毫升,T75 烧瓶 2.5 毫升),确保完全覆盖细胞层。让细胞在室温下孵育 10 分钟。孵育后,将悬浮细胞和粘附细胞混合并离心。离心后,小心重悬细胞团,并将细胞悬浮液转移到装有新鲜培养基的新烧瓶中。
- Seeding density
- 以5×10⁵活细胞/毫升浓度启动新培养。在1-2×10⁶细胞/毫升浓度下进行传代培养。最高细胞密度为1-2×10⁶细胞/毫升。
- Fluid renewal
- 每周 2 至 3 次
- Post-thaw recovery
- 解冻后,让细胞从冷冻过程中恢复至少 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。
08Donor
- Donor age
- 61 年
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。
