01General information

Description

JJN-3 是一种从一名 57 岁白人女性患者的骨髓中建立的人多发性骨髓瘤细胞系。 该细胞系以悬浮状态生长,呈单个圆形至椭圆形细胞,偶尔呈现多核形态。JJN-3 携带 NRAS p.Gln61Lys 激活突变,这反映了骨髓瘤中常见的 RAS 信号通路失调。 该细胞系源自浆细胞,保留了恶性浆细胞的免疫表型特征(包括 CD38 和 CD138 的表达),已被用于众多关于骨髓瘤生物学和药物敏感性的研究。

JJN-3 适用于多发性骨髓瘤生物学、NRAS Q61K 致癌信号传导、抗骨髓瘤药物评估(硼替佐米、来那度胺、达拉图单抗、埃洛图单抗)、浆细胞分化以及骨髓微环境相互作用的研究。 它是公认的多发性骨髓瘤参考细胞系之一,适用于研究 CD38 靶向免疫疗法、IMiD 的作用,以及 RAS 突变型多发性骨髓瘤中蛋白酶体抑制剂的反应。

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
作为冷冻保存培养基,我们使用完全生长培养基+10% DMSO,以获得足够的解冻后存活率。
Storage conditions

如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。

Shipping conditions

冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。
