01General information

Description

RBL-2H3 细胞系已成为研究肥大细胞生理学的重要工具。RBL-2H3细胞表达大鼠肥大细胞蛋白酶II(RMCP-II)和c-kit受体酪氨酸激酶,使其成为肥大细胞的潜在模型。然而,有关RBL-2H3细胞的数据却相互矛盾,有时甚至具有误导性。

RBL-2H3 细胞已被广泛用于研究肥大细胞功能的各个方面,包括脱颗粒、肥大细胞稳定剂以及 FceRI 受体与细胞骨架的相互作用。它们表达高亲和性 IgE 受体,可被激活以分泌组胺和其他介质。培养 RBL-2H3 细胞相对容易,培养时间越长,细胞密度越高。

脱颗粒是 RBL-2H3 细胞的一个主要特征,与肥大细胞和嗜碱性粒细胞类似。当过敏原交联其与 IgE 结合的 FceRI 受体时,RBL-2H3 细胞会释放预先形成和新合成的介质,从而导致免疫过敏反应。RBL-2H3 细胞的脱颗粒功能也为嗜碱性粒细胞的脱颗粒功能提供了启示。这些细胞在非免疫刺激下也会发生脱颗粒反应,MMC、RBL-2H3 和 CTMC 之间存在差异。
钙在 RBL-2H3 细胞脱颗粒中的作用非常重要。钙离子诱导剂 A23187 可增加细胞内钙水平,诱导 RBL-2H3 细胞脱颗粒,与肥大细胞和嗜碱性粒细胞相似。一些研究将 RBL-2H3 细胞描述为血清素释放细胞系。

05Handling and culture

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
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。
Fluid renewal
每周 2 至 3 次
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 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.

06Quality control and cryopreservation

Sterility

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。

Freeze medium
我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
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。
