01General information

Description

BA/F3 细胞系来源于 BALB/c 小鼠品系的小鼠前 B 细胞,是药物发现和开发的基石,其中 BaF3 细胞通常用于测试针对致癌激酶的小分子抑制剂的疗效。

Baf3 是一种依赖 IL-3 的细胞系,其细胞形态为单个圆形,且存在多态性。Ba/F3 细胞用于 F3 转化试验和 Ba/F3 增殖试验。通过 F3 转化试验,可以探索特定基因改变如何使细胞独立于 IL-3 生长,从而显示致癌潜力。这些细胞依靠细胞因子受体 IL-3 的细胞因子信号来维持增殖,因此 baf3 增殖试验是研究细胞因子剥夺效应以及细胞因子信号在细胞存活和生长中的作用的绝佳工具。

事实证明,BA/F3细胞在激酶致癌基因评估和小分子激酶抑制剂测试方面非常有价值。例如,表达慢性髓性白血病(CML)特有的BCR-ABL致癌基因的Ba/F3细胞已被用于测试伊马替尼等酪氨酸激酶抑制剂(TKIs)的有效性。Ba/F3细胞还适用于高通量筛选和耐药机制探索,这对于了解癌症相关激酶组突变的动态和开发克服靶向疗法耐药性的策略至关重要。

总之,BA/F3 细胞系具有独特的特征和生物学功能,是激酶药物发现的重要资源。

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 5% 热灭活 FBS、10 ng/mL 小鼠 IL-3
Subculturing
通过定期添加或更换培养基来维持细胞培养。初始培养时细胞密度应为5×10⁵个细胞/毫升,并保持细胞浓度在3×10⁵至1×10⁶个细胞/毫升范围内以获得最佳生长效果。
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.

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。
