01General information

Description

JJN-3 是一種從一名 57 歲白人女性患者的骨髓中建立的人類多發性骨髓瘤細胞系。 該細胞系以懸浮方式生長,呈單個圓形至橢圓形細胞,偶爾呈現多核形態。JJN-3 攜帶 NRAS p.Gln61Lys 活化突變,反映出多發性骨髓瘤中常見的 RAS 路徑失調。 這是一種源自漿細胞的多發性骨髓瘤細胞系,保留了惡性漿細胞的免疫表型特徵(包括 CD38 和 CD138 的表達),並已被廣泛應用於多發性骨髓瘤生物學及藥物敏感性研究。

JJN-3 適用於多發性骨髓瘤生物學、NRAS Q61K 致癌訊號傳導、抗骨髓瘤藥物評估(硼替佐米、來那度胺、達拉圖單抗、艾洛珠單抗)、漿細胞分化以及骨髓微環境相互作用等研究。 它是公認的多發性骨髓瘤參考細胞系之一,適用於研究 CD38 靶向免疫療法、IMiD 作用,以及 RAS 突變型多發性骨髓瘤中蛋白酶體抑制劑的反應。

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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.

  7. Follow the procedure described under Post-Thaw Recovery

07Quality control and cryopreservation

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基加上 10% 的二甲基亞砜(DMSO),以確保解凍後的細胞存活率達到適當水準。
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。
