01General information

Description

L-929-GFP细胞是小鼠L-929成纤维细胞系的荧光标记衍生物,该细胞系最初是从成年小鼠的皮下结缔组织中建立的。 其亲本 L-929 细胞系是生物医学研究中应用最广泛的小鼠成纤维细胞模型之一,其特征为贴壁生长、纺锤形形态以及强大的增殖能力。 L-929 细胞广泛应用于细胞毒性、炎症、细胞外基质生物学以及宿主-病原体相互作用的研究,也常用于肿瘤坏死因子-α(TNF-α)等细胞因子的生产和生物测定。

L-929-GFP细胞中绿色荧光蛋白(GFP)的稳定表达,使得能够实时直接观察和定量追踪成纤维细胞的行为。这些细胞特别适用于基于荧光的应用,包括迁移实验、共培养实验、组织工程研究以及活细胞成像。 L-929-GFP细胞在保留亲本成纤维细胞系核心生物学特性的同时,还增强了监测细胞定位、增殖以及在复杂细胞环境中的相互作用的能力。因此,它们可作为研究基质细胞动力学、伤口愈合过程、生物材料相容性以及免疫介导的细胞毒性反应的多功能模型。

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)条件下作为多克隆细胞群维持。S1/BSL-1 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.

Supplements
在培养基中添加 10% FBS
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。
