ARH-77

ARH-77 細胞系是一種源自一名 33 歲女性患者外周血的人類細胞系，該患者罹患漿細胞白血病——這是一種影響骨髓中漿細胞的癌症。 ARH-77 細胞的特徵在於其 B 淋巴母細胞樣表型，這使得該細胞系特別適用於研究 B 細胞的成熟與功能，以及漿細胞白血病的病理機制。由於該細胞系經由愛潑斯坦-巴爾病毒（EBV）轉化，因此也常被用於與 EBV 相關的研究。

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。
