01General information

Description

PY8119-GFP细胞是小鼠PY8119乳腺癌细胞系的荧光标记衍生物,该细胞系源自小鼠模型中的自发性乳腺肿瘤。 亲本 PY8119 细胞系通常与基因工程改造的小鼠乳腺癌模型相关,并用于在同基因背景下一研究肿瘤进展、免疫相互作用和治疗反应。 绿色荧光蛋白(GFP)的稳定表达使肿瘤细胞的行为得以直接可视化,便于在体外和体内实时追踪细胞的增殖、迁移和细胞间相互作用。

GFP修饰使PY8119-GFP细胞特别适合用于活细胞成像、活体显微镜观察以及在免疫功能正常的小鼠模型中进行转移研究。这些细胞保留了亲本细胞系的关键特征,包括侵袭性生长以及移植到同基因宿主时形成肿瘤的能力。 因此,PY8119-GFP细胞被广泛用于研究肿瘤与免疫系统的动态关系、评估抗癌疗法,以及探究侵袭和转移的机制。然而,与所有荧光修饰细胞系一样,建议进行仔细验证,以确保GFP的表达不会改变细胞的基础行为。

基因修饰:通过复制缺陷型慢病毒转导进行稳定修饰,以表达 ZsGreen1 绿色荧光蛋白报告基因;在嘌呤霉素筛选(1–5 µg/mL)下作为多克隆细胞群维持。S1/BSL-1 生物安全等级。

GMO status details
GMO-S1: This cell line contains a stably integrated ZsGreen1 green fluorescent protein reporter 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。
