HAL-01

HAL-01 细胞系来自一名被诊断为急性淋巴细胞白血病（ALL），特别是 L2 亚型的女性青少年的外周血。该细胞系尤其值得注意的是含有t(17;19)(q22;p13)染色体易位，导致TCF3-HLF（E2A-HLF）融合基因。这一基因特征在白血病研究中至关重要，因为它影响白血病细胞的行为，包括其生长、分化和对疗法的反应等方面。

HAL-01 细胞系中 TCF3-HLF 融合基因的存在，使其成为肿瘤研究的宝贵资源，尤其是在白血病发生机制和白血病靶向疗法开发方面。该基因编码的融合蛋白参与基因转录的调控，与患者的不良预后有关，这突出了该细胞系在急性淋巴细胞白血病的治疗开发和预后研究中的重要性。

37°C, 5%_CO2, 加湿环境。

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.

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。

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。

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。
