01General information

Description

HeLa-Luc细胞是人类HeLa宫颈腺癌细胞系的生物发光衍生物,经过基因工程改造后可持续表达荧光素酶报告基因。 在添加荧光素底物后,这些细胞会发出可量化的发光信号,该信号与存活细胞数量及代谢活性直接相关。这一特性使得在体外实验和体内成像应用中,能够对肿瘤细胞的增殖、存活和扩散进行灵敏、无创的监测。HeLa-Luc细胞保留了亲本HeLa细胞特有的强健生长特性和上皮形态,同时为纵向实验分析提供了额外的光学读数。

由于具有表达荧光素酶的表型,HeLa-Luc细胞特别适用于免疫缺陷动物模型中的异种移植和转移研究,在这些研究中,可通过实时生物发光成像随时间推移追踪肿瘤负荷和治疗反应。 在细胞基检测中,这些细胞被广泛应用于高通量药物筛选、细胞毒性测试、基因递送系统的评估,以及癌细胞信号传导和凋亡的研究。稳定的报告基因表达还支持在共培养系统以及需要动态监测细胞存活率或转录活性的实验模型中进行可重复的定量分析。

与亲本HeLa细胞一样,HeLa-Luc细胞表现出基因组不稳定性和高增殖能力,这是与人乳头瘤病毒18型(HPV-18)相关的转化型宫颈癌细胞的特征。不同实验室或商业来源在实验条件、荧光素酶载体设计、启动子选择及筛选策略方面可能存在差异,这可能会影响报告基因的发光强度和长期表达稳定性。 因此,研究人员在进行大规模实验应用前,应在其特定的培养和检测条件下验证荧光素酶活性、生长动力学及表型一致性。

GMO status details
GMO-S1: This cell line contains a stably integrated firefly luciferase reporter cassette (Luc2, codon-optimized) introduced via replication-incompetent lentiviral transduction. The resulting polyclonal cell population was maintained under puromycin selection (1–5 µg/mL). S1 containment is required. This classification applies only within Germany and may differ elsewhere.

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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.

  7. Follow the procedure described under Post-Thaw Recovery

07Quality control and cryopreservation

Freeze medium
作为冷冻保存培养基,我们使用完全生长培养基+10% DMSO,以获得足够的解冻后存活率。
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。
