01General information

Description

SW620-Luc 是人类 SW620 转移性结肠腺癌细胞系的生物发光衍生物,经基因工程改造后可稳定表达萤火虫荧光素酶报告基因。其亲本细胞系 SW620 源自与建立 SW480 细胞系相同的患者的淋巴结转移灶,这使得能够对结直肠癌生物学进行原发灶与转移灶的配对比较研究。 SW620细胞呈现上皮样形态,并与SW480具有相同的致癌关键突变,包括KRAS G12V、TP53 R273H和P309S以及APC截短突变,但表现出更强的间质特征和更强的侵袭潜力,这与其转移性起源相一致。 SW620 被广泛用于研究结直肠癌转移、上皮-间质转化 (EMT) 以及治疗耐药机制。

SW620-Luc中稳定的荧光素酶整合,使得在免疫缺陷宿主中的异种移植和实验性转移模型中,能够对肿瘤负荷进行灵敏、定量的生物发光成像(BLI)。发出的信号与存活肿瘤细胞数量相关,支持对肿瘤植入、生长动力学、肝脏定植和淋巴结播散的纵向监测。 SW620-Luc在研究结直肠癌的转移进展、评估抗转移药物以及与匹配的原发SW480细胞系进行体内比较研究方面具有特别重要的价值。

SW620-Luc保留了亲本SW620细胞系的分子特征和转移表型,包括KRAS和TP53突变。荧光素酶修饰显著提高了实验通量,并增强了治疗有效性体内药效学评估的灵敏度。研究人员在进行大规模临床前应用前,应根据其特定实验条件验证荧光素酶活性、突变谱及生长动力学。

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.

Dissociation reagent
Accutase
Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。

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。
