01General information

Description

A20 細胞系源自小鼠的網狀細胞肉瘤,廣泛應用於免疫學及癌症研究。網狀細胞肉瘤是一種 B 細胞淋巴瘤,而 A20 細胞為研究 B 細胞淋巴瘤的生物學特性及免疫反應提供了寶貴的模型。 這些細胞對於探究 B 細胞的發育、活化、訊號傳導機制,以及腫瘤細胞與免疫系統之間的相互作用,特別有用。此外,A20 細胞在針對細胞因子產生與功能的研究中扮演關鍵角色,而細胞因子對於免疫調節至關重要。

A20 細胞呈現淋巴母細胞形態,並表達 B 細胞特有的表面標記,包括表面免疫球蛋白及主要組織相容性複合體(MHC)分子。 研究人員利用 A20 細胞來研究抗原呈遞、B 細胞受體訊號傳導,以及各種細胞因子在免疫反應中的作用。這些細胞對於開發和測試旨在治療 B 細胞淋巴瘤及其他血液惡性腫瘤的免疫療法(例如單克隆抗體和檢查點抑制劑)也至關重要。 此外,A20 細胞亦可作為前臨床研究中評估新型治療藥物療效與安全性的模型。A20 細胞在免疫學研究及理解 B 細胞病理生理學方面的應用價值,凸顯了其在推動癌症研究及開發新治療策略方面的重要性。

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% 經熱滅活的胎牛血清 (FBS),並添加 2.5 g/L 葡萄糖及 10 mM HEPES
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。
