01General information

Description

WEHI-3B 细胞系是一种小鼠白血病细胞系,被广泛用作研究骨髓单核细胞分化和白血病病理生理学的模型。这些细胞最初来源于 BALB/c 小鼠,具有髓系祖细胞的特征,在研究造血分化和调节方面发挥了重要作用。WEHI-3B 细胞系对于研究生长因子对白血病细胞的影响尤为重要,已被用于评估包括集落刺激因子在内的各种物质的造血活性。

这种细胞系不仅在白血病研究中具有重要意义,还可作为研究巨噬细胞和粒细胞功能的工具,因为它能在特定实验条件下分化成这些细胞类型。使用 WEHI-3B 细胞进行的研究有助于更好地了解细胞分化的分子途径以及基因改变对白血病进展的影响。此外,WEHI-3B 细胞系还被用于测试单核细胞集落刺激因子(M-CSF)和粒细胞-巨噬细胞集落刺激因子(GM-CSF)的生物活性,突出了它在血液学研究中的多功能性和实用性。

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
  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。
