HEK293-FOLR1细胞系是一种稳定的重组HEK293细胞系,经过工程改造可在细胞内以中高水平表达FOLR1受体,每细胞约15,000个分子。该细胞系采用inscreenex的“着陆点”技术开发,确保FOLR1基因能精确且可重复地整合到特定的、预先验证过的基因组位点上。 FOLR1,又称叶酸受体α(FRα)或FBP,是一种GPI锚定膜蛋白,对叶酸具有强亲和力,可促进其向细胞内的转运。FOLR1在某些癌症(如卵巢癌、乳腺癌和非小细胞肺癌)中显著过表达,使其成为免疫肿瘤疗法(包括CAR-T细胞疗法和双特异性抗体)的重要靶点。

通过流式细胞术结合靶向特异性抗体,证实了该细胞系中 FOLR1 的表达,确保了整个细胞群体中受体密度的可靠性和一致性。

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、1 mM 丙酮酸钠、10 mM HEPES 和 1% NEAA。加入基因素(G418-硫酸酯),使最终浓度达到 1 mg/mL。
Dissociation reagent
胰蛋白酶-EDTA
Subculturing
常规粘附细胞培养:吸出粘附细胞中的旧培养基,并用 PBS 冲洗以去除残留的培养基。吸出 PBS 后,根据培养皿大小加入适量的胰蛋白酶/EDTA 溶液(如 T25 烧瓶 1 毫升,T75 烧瓶 3 毫升),室温或 37°C 孵育直至细胞分离(5-10 分钟)。在显微镜下观察分离情况,必要时轻轻拍打容器以释放细胞。细胞分离后,加入完全培养基以灭活胰蛋白酶/EDTA,轻轻重悬细胞,然后将等分的细胞悬浮液转移到装有新鲜培养基的新培养皿中。将培养皿放入温度为 37°C、二氧化碳浓度为 5%的培养箱中,每 2-3 天更换一次培养基。
Split ratio
1 到 5
Seeding density
2至4×10⁴个细胞/平方厘米
Fluid renewal
每周 2 至 3 次
Post-thaw recovery

解冻后,按 1:2 至 1:3 的比例将细胞分装在 T25 烧瓶中,让细胞从冷冻过程中恢复并附着至少 24 小时。

为了在解冻细胞后获得最佳的附着力和存活率,我们建议在冷冻恢复后使用涂有胶原蛋白的烧瓶或平板进行首次播种。随后的细胞常规培养不需要胶原涂层。

Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. 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.

  3. 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.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. 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.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. 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.

  8. 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。
