01General information

Description

RPMI 8226 細胞是一種人類骨髓瘤細胞系,於 1966 年從一名 61 歲男性多發性骨髓瘤患者的外周血中建立。 該細胞系以研發機構「羅斯威爾帕克紀念研究所」(Roswell Park Memorial Institute,簡稱 RPMI)命名,而數字 8226 則代表其在細胞庫中的特定編號。

RPMI 8226 細胞系是研究多發性骨髓瘤及相關漿細胞生物學、免疫學研究與癌症治療的重要模型系統。 已知 RPMI 8226 細胞會產生並分泌免疫球蛋白的 kappa 輕鏈,此特性常被運用於研究中,以探討抗體的產生與分泌機制。

RPMI 8226 細胞呈現多種染色體異常,這正是多發性骨髓瘤細胞的典型特徵。這些異常包括影響各種致癌基因和腫瘤抑制基因的易位、缺失及擴增。

人類骨髓瘤細胞系 RPMI 8226 廣泛應用於藥物發現與開發研究,並已被用於探究藥物抗性途徑及評估聯合療法。

總而言之,RPMI 8226 細胞為多發性骨髓瘤研究提供了關鍵的體外模型,有助於探究該疾病背後的生物學與分子機制,並開發治療策略。

06Handling 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)
Dissociation reagent
Accutase
Subculturing
將懸浮細胞收集至 15 毫升試管中,並用不含鈣和鎂的 PBS 輕柔地洗滌貼壁細胞(T25 培養瓶使用 3-5 毫升,T75 培養瓶使用 5-10 毫升)。 加入 Accutase(T25 培養瓶使用 1–2 毫升,T75 培養瓶使用 2.5 毫升),確保完全覆蓋細胞層。讓細胞於室溫下孵育 10 分鐘。 孵育完成後,將懸浮細胞與貼壁細胞合併並進行離心。離心後,小心地將細胞沉澱重新懸浮,並將細胞懸液轉移至裝有新鮮培養基的新培養瓶中。
Seeding density
以 5 × 10⁵ 個活細胞/毫升的濃度建立新培養。以 1–2 × 10⁶ 個細胞/毫升的濃度進行傳代培養。最大細胞密度為 1–2 × 10⁶ 個細胞/毫升。
Fluid renewal
每週 2 至 3 次
Post-thaw recovery
解凍後,請讓細胞有至少 24 小時的時間從冷凍過程中恢復。
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

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。
