01General information

Description

Walker-256 细胞系是一种大鼠癌细胞系,广泛用于癌症研究,特别是肿瘤生物学和化疗研究。该细胞系源自大鼠乳腺癌,以其侵袭性转移行为而著称,是研究癌症进展和转移的重要模型。它已被广泛用于研究体内肿瘤生长机制和抗癌药物的疗效。

Walker-256 细胞对各种环境的适应性很强,可以在多种不同的动物模型中生长,这有助于在系统背景下研究癌症生物学。这种细胞系对药理学研究,特别是与开发和测试新化疗药物有关的研究非常有用。研究人员利用 Walker-256 评估药物诱导的细胞毒性,探索新型治疗化合物的潜在作用机制。Walker-256 在研究中的广泛应用为了解肿瘤的生长动态以及肿瘤对宿主生理机能的系统性影响提供了重要依据。

04Handling 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% 热灭活 FBS、0.01 mg/mL 胰岛素、4.5 g/L 葡萄糖、1 mM 丙酮酸钠和 10 mM HEPES
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.

05Quality 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。
