01General information

Description

B-LCL-CDG1 是一種源自被診斷為 PMM2-CDG(一種先天性糖基化障礙,簡稱 CDG)患者的 EBV 轉化 B 淋巴細胞系。 這種罕見的代謝性疾病源於 *PMM2* 基因的突變,該基因編碼磷酸甘露糖轉化酶 2(PMM2),這是糖基化途徑中一種不可或缺的酶。 *PMM2* 基因的突變會干擾糖基化寡糖鏈的合成,導致組織和血液中各種糖蛋白及糖鞘脂的糖基化過程出現缺陷。此疾病以多系統性表現為特徵,常影響神經、肝臟及內分泌功能。

作為一種經 EBV 轉化而成的淋巴母細胞樣細胞系,B-LCL-CDG1 為研究 *PMM2* 缺乏所導致的分子與細胞層面後果,提供了一個極具價值的體外模型。 此細胞系可用於研究糖基化缺陷、PMM2 酶活性,以及潛在的治療干預措施,包括基因矯正與底物補充。B-LCL-CDG1 與其他源自 CDG 患者的細胞系一同,成為理解 CDG 病理生理學及評估這些疾病新型治療策略的重要資源。

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% 經熱滅活的胎牛血清
Subculturing
透過定期添加或更換培養基來維持培養。起始培養時,細胞密度應為 2 × 10⁵ 個細胞/毫升,並將細胞濃度維持在 1 × 10⁵ 至 5 × 10⁵ 個細胞/毫升的範圍內,以達到最佳生長效果。

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。
