01General information

Description

P388 是一種源自 DBA/2 小鼠自發性淋巴細胞白血病的鼠源性淋巴瘤細胞系。該細胞系廣泛應用於癌症研究,特別是白血病研究及抗癌化合物的測試。 P388 細胞以懸浮方式生長,在最佳培養條件下,其倍增時間約為 24 小時。該細胞的特徵在於增殖迅速且對化療藥物高度敏感,使其成為評估新型癌症治療方法療效的寶貴工具。

P388 細胞表達淋巴系細胞的典型標記物,包括表面免疫球蛋白及與 B 細胞相關的各種細胞表面抗原。 研究人員常將此細胞系接種至小鼠體內,作為體內模型來研究腫瘤生長、轉移及對治療的反應。此外,P388 細胞系亦可用作研究白血病分子機制(例如特定致癌基因與腫瘤抑制基因的作用)的模型。

儘管 P388 細胞系被廣泛應用,但仍存在某些限制,例如與人類相關性不足,以及長期培養期間可能發生基因漂變。因此,研究人員常會將涉及 P388 細胞的研究與其他模型相輔相成,以全面理解白血病的生物學特性及治療反應。

05Handling and culture

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Subculturing
懸浮細胞:使用新鮮培養基以移液管吸取,將細胞從基質上移除。若要獲得單一細胞,請將懸浮液多次通過 22 號針頭,並分裝至新的培養瓶中。
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 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

透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。

為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
Storage conditions

若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。

Shipping conditions

冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。
