01General information

Description

Sp2/0-Ag14细胞系通常被称为Sp2/0,是一种广泛用于生产单克隆抗体的小鼠骨髓瘤细胞系。该细胞系源于 BALB/c 小鼠品系,是通过将免疫小鼠的脾脏细胞与缺乏次黄嘌呤-鸟嘌呤磷酸核糖转移酶(HGPRT)的骨髓瘤细胞融合而成。这种缺陷使 Sp2/0 细胞无法在 HAT(次黄嘌呤、氨蝶呤、胸腺嘧啶)培养基中存活,而当与免疫小鼠的脾脏细胞融合时,这一特性对杂交瘤的筛选至关重要,因为只有杂交瘤细胞才能在这种选择性培养基中增殖。

Sp2/0-Ag14 细胞系在细胞培养中具有稳定性和稳健性的特点,使其成为杂交瘤生产的首选宿主。这些细胞不产生免疫球蛋白是一个重要特征,因为它能防止内源性免疫球蛋白的分泌,以免干扰杂交瘤产生的单克隆抗体。这种细胞系已被广泛用于科学研究和工业应用,用于产生针对多种抗原的单克隆抗体。所产生的抗体可用于研究、诊断和治疗,这凸显了 Sp2/0 细胞系在生物技术和制药业中的重要作用。

06Handling and culture

Culture medium
DMEM,w:4.5 克/升葡萄糖,w:4 毫摩尔 L-谷氨酰胺,w:3.7 克/升 NaHCO3,w:1.0 毫摩尔丙酮酸钠(Cytion 编号 820300a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Subculturing
在微离心管中收集带有漂浮细胞的培养基。用不含钙和镁的 PBS 冲洗粘附的细胞(T25 细胞培养皿用 3-5 毫升 PBS,T75 细胞培养皿用 5-10 毫升)。加入 Accutase(每个 T25 细胞培养瓶 1-2 毫升,每个 T75 细胞培养瓶 2.5 毫升),细胞片必须完全覆盖。在 37 摄氏度下孵育 10 分钟。将漂浮的细胞和分离的细胞混合在一个试管中,300xg 离心 3 分钟。小心地将细胞重悬于新鲜培养基中,然后分装到装有新鲜培养基的新培养瓶中。
Seeding density
保持细胞密度在5×10⁴至5×10⁶活细胞/毫升之间。
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.

07Quality 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。
