01General information

Description

Hep3B 細胞系源自一名 8 歲罹患肝癌的兒童,是研究人類肝癌細胞及其對各種治療藥物反應的關鍵模型。Hep3B 細胞含有整合的 B 型肝炎病毒基因組,並因其獨特的遺傳與表型特徵,在探究藥物反應差異方面扮演著不可或缺的角色。

Hep3B 人肝癌細胞系以其廣泛表達肝臟特異性蛋白質(如甲胎蛋白(AFP)、白蛋白及其他各種標記物)而聞名,使其成為藥物代謝與肝毒性研究中不可或缺的工具。 這種廣泛表達的蛋白質陣列,使得研究人員能夠全面評估肝癌細胞如何與治療藥物相互作用並代謝這些藥物。

Hep 3B 細胞系及其衍生細胞系能夠追蹤體內腫瘤的生長與轉移,有助於研究肝癌的進展以及潛在治療方法的療效。

Hep 3B 細胞系作為一項關鍵資源,在深化我們對肝癌生物學的理解以及開發更有效的治療策略方面,扮演著舉足輕重的角色。

Protein expression
甲胎蛋白(Alpha-Fetoprotein)、B型肝炎表面抗原(HbsAg)、白蛋白、α2巨球蛋白(Alpha-2-Macroglobulin)、 α-1抗胰蛋白酶(α-1-Antitrypsin)、轉鐵蛋白、α-1抗胰凝乳蛋白酶(α-1-Antichymotrypsin)、血紅蛋白結合蛋白、銅藍蛋白

06Handling and culture

Culture medium
EMEM(MEM Eagle),含 2 mM L-谷氨醯胺,含 2.2 g/L NaHCO₃,含 EBSS(Cytion 產品編號 820100a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS 和 1% NEAA
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.

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。
