常见问题解答 (FAQ)

我不慎将我的脂质体试剂留在了室温条件下,还能继续使用吗?

可以,我们所有的脂质体转染试剂均能够在室温下稳定保存数月。

你们是否为悬浮细胞(如Jurkat细胞)的转染操作提供专门试剂?

可尝试使用Lipofectamine 3000来转染Jurkat细胞,但是如果使用Neon电转系统可获得高达98%的转染效率。

反向转染与正向转染之间区别是什么?我该如何选择?

在正向转染过程中,细胞铺于培养孔之中,用通常的方式制备转染复合物并在第二天将其加入细胞培养物中。在反向转染过程中,在培养孔之中制备转染复合物,之后再加入细胞与培养基。反向转染比正向转染过程更迅速,因此是高通量转染的理想之选。在非高通量的转染操作中,通常正向转染对于大多数类型的细胞转染效果更佳。

转染过程中的培养基可使用抗生素么?

可以,转染过程中可在培养基中添加抗生素(青霉素-链霉素)。我们对多个细胞系在含与不含抗生素的培养基中的转染效果进行了比较,同时评估其转染效率和细胞毒性,结果显示并无差别。不过,某些细胞类型对转染过程敏感或可能出现细胞毒性方面的问题,此时省略抗生素可能会有助于改善结果。对稳定转染而言,转染操作后至少等待48小时以上,再加入选择性抗生素。

在脂质体转染过程中必须使用无血清的培养基么?

脂质体转染过程中不是必须采用无血清培养基。不过,脂质:核酸复合物一定要在无血清的条件下配制,因为(血清中的)蛋白质可能会干扰复合物的形成。一旦复合物形成,即可直接加至含血清培养基中的细胞中。

Abstract
Induction of bacterial lipoprotein tolerance is associated with suppression of toll-like receptor 2 expression.
Authors:Wang JH, Doyle M, Manning BJ, Di Wu Q, Blankson S, Redmond HP.
Journal:J Biol Chem
PubMed ID:12133836
'Tolerance to bacterial cell wall components including lipopolysaccharide (LPS) may represent an essential regulatory mechanism during bacterial infection. Two members of the Toll-like receptor (TLR) family, TLR2 and TLR4, recognize the specific pattern of bacterial cell wall components. TLR4 has been found to be responsible for LPS tolerance. However, the ... More
Safety and short-term toxicity of a novel cationic lipid formulation for human gene therapy.

'Among the potential nonviral vectors for human gene therapy are DNA-liposome complexes. In a recent clinical study, this delivery system has been utilized. In this report, a novel cationic lipid, dimyristyloxypropyl-3-dimethyl-hydroxyethyl ammonium (DMRIE), has been substituted into the DNA-liposome complex with dioleoyl phosphatidylethanolamine (DOPE), which both improves transfection efficiencies and ... More
Nitrosative Stress-induced Apoptosis through Inhibition of NF-kappa B.
Authors: Marshall Harvey E; Stamler Jonathan S;
Journal:J Biol Chem
PubMed ID:12091382
'Nitrosative stress produced by cytokines predisposes to apoptotic cell death. However, the molecular mechanism by which this occurs is not well understood. We have shown previously that nitric oxide (NO) regulates the activity of the anti-apoptotic transcription factor NF-kappaB. Here we demonstrate that the inhibition of NF-kappaB by NO sensitizes ... More

'Cationic liposome-mediated in vivo gene transfer represents a promising approach for somatic gene therapy. To assess the most suitable liposome for gene delivery into a wide range of organs and fetuses in mice, we have explored several types of cationic liposomes conjugated with plasmid DNA carrying the beta-galactosidase gene through ... More
BiZyme: a novel fusion protein-mediating selection of vaccinia virus recombinants by fluorescence and antibiotic resistance.

'Recombinant vaccinia virus is a useful and powerful tool for the expression and study of foreign genes. Methods that are currently available for the selection of vaccinia virus recombinants include the restoration of viral plaque-forming phenotype, the replication of viral DNA in the presence of BUdR or mycophenolic acid, and ... More
