01General information

Description

Raji 細胞是由 R.J.V. Pulvertaft 於 1963 年從伯基特淋巴瘤中建立的一種淋巴母細胞樣細胞系。 由於這些細胞高度表達人類CD19,且該分子可作為共受體,降低抗原對B細胞受體(BCR)的刺激閾值,因此Raji細胞在免疫學研究中被廣泛應用。Raji細胞為非黏附性細胞,在懸浮培養中以單個或成對的形式自由漂浮生長。

這些細胞的倍增時間為23.2小時,直徑相對較小,範圍介於5至8微米之間。Raji細胞的特徵之一是缺乏分化能力,因此會形成由數百個單一細胞組成的巨大聚集体。 這些細胞為二倍體,在男性二倍體幹細胞系中具有穩定的核型,即46。

此外,Raji 細胞對小兒麻痺病毒和水疱性口炎病毒具有部分抗性。Raji 細胞高度表達人類 CD19,並已被確認為非霍奇金 B 細胞淋巴瘤中抗 hCD19-CD3 雙特異性抗體的臨床靶點。 此外,在 Raji 伯基特淋巴瘤細胞系及原發性淋巴瘤中亦已檢測到 BCMA 的表達,使其成為免疫學家的重要研究領域。

05Expression and susceptibility

Products
當受到紐卡素病病毒刺激時,這些細胞可能會產生干擾素。

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
透過移液管上下吸放,輕柔地將燒瓶中的細胞懸浮液均質化,然後取一份具代表性的樣本,以測定每毫升的細胞密度。使用新鮮培養基將懸浮液稀釋至細胞濃度為 1 × 10⁵ 個細胞/毫升,並將調整後的懸浮液分裝至新的燒瓶中,以供進一步培養。
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。
