CLS-145 細胞

CLS-145 細胞系是從一名經診斷患有惡性腫瘤的患者身上取得的腫瘤組織碎片所建立的原代培養細胞系。該細胞系的建立過程未經患者接受任何先前的治療干預，因此保留了腫瘤細胞原生的遺傳及表型特徵。 未曾接受過任何治療這一點至關重要，因為這能確保細胞特性未因化療藥物或放射治療而改變，從而為研究腫瘤的自然進展與特徵提供更精確的模型。

37°C，5% CO_₂，加濕環境。

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.

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。

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。

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。
