01General information

Description

Lenti-X293T细胞系源自人胚胎肾293T细胞系,经专门工程改造与优化,可高效生产慢病毒载体。与亲本293T细胞相同,该细胞系稳定表达SV40大T抗原,能促进含SV40复制起始点的质粒进行环状复制,显著提升瞬时转染效率。 Lenti-X293T细胞在标准血清补充培养条件下呈现黏附性上皮形态及强劲生长特性,支持高密度培养,适用于大规模病毒生产流程。

该细胞系经筛选可使用磷酸钙、脂质或聚合物试剂实现卓越转染性能,与传统HEK293T细胞相比能持续产出更高滴度的慢病毒。 其增强的病毒产出源于优化细胞生理特性:在与适配包装及包膜构建体共转染时,可高效摄取质粒、强力表达外源基因,并有效组装释放无复制能力的慢病毒颗粒。因此Lenti-X293T细胞广泛应用于基因递送、基因编辑及稳定细胞系构建中的第三代慢病毒载体制备。

Lenti-X293T细胞保留了HEK293衍生系统的高水平重组蛋白表达及瞬时基因表达研究的通用优势。其稳定的生长特性和可重复的性能使其既适用于小规模研究,也适用于可扩展的生产环境——前提是遵循慢病毒系统的标准生物安全及载体包装指南。

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。
