01General information

Description

NRK-52E 細胞系源自大鼠的正常腎臟,是一種代表近端腎小管上皮細胞的類上皮細胞系。該細胞系廣泛應用於腎臟學研究,特別是腎臟生理學、毒理學及病理生理學的研究。 NRK-52E 細胞呈現具緊密連接的特徵性上皮形態,使其適合用於體外模擬腎小管功能及屏障完整性。

NRK-52E 細胞在研究凋亡、細胞修復及離子轉運機制方面發揮了關鍵作用。 舉例而言,該細胞系曾被用於探究蛋白質磷酸酶抑制劑「岡田酸」的作用,揭示了其在誘導涉及染色質凝集、鈣離子內流及線粒體變化的凋亡途徑中的角色。這些研究為理解腎臟在受損或疾病期間細胞死亡與存活機制的調控提供了新見解。

此外,NRK-52E 細胞還被用於評估各種實驗設置(例如模擬生理流動條件的微流體系統)下的腎上皮細胞離子轉運與屏障特性。 這包括對氯化鈉重吸收及跨上皮電阻的研究,這些對於理解腎臟生理學中的電解質與水平衡至關重要。這些特性使 NRK-52E 成為探索腎小管細胞生物學及腎臟疾病治療干預措施的可靠模型。

05Handling and culture

Culture medium
DMEM:Ham's F12(1:1),重量比:3.1 g/L 葡萄糖,重量比:2.5 mM L-谷氨酰胺,重量比:15 mM HEPES, w: 0.5 mM 丙酮酸鈉,w: 1.2 g/L NaHCO₃(Cytion 產品編號 820400a)
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
從貼壁細胞中移除舊培養基,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶使用3-5毫升PBS,T75培養瓶則使用5-10毫升。 接著,用 Accutase 完全覆蓋細胞,T25 培養瓶使用 1–2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8–10 分鐘,使其脫附。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。
Fluid renewal
每週 2 至 3 次
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。
