Oligofectamine™ 转染试剂是一种专有制剂,用于将寡核苷酸和短干扰 RNA (siRNA) 转染至真核细胞。Oligofectamine™ 转染试剂与寡核苷酸形成稳定复合物,允许以高度特异性但无毒的方式有效转染真核细胞。Oligofectamine™ 试剂适用于细胞核和细胞质靶点,并可转染多种细胞系,包括 CHO、HEK-293、NIH 3T3 和 HeLa。

使用 Oligofectamine™ 转染试剂
Oligofectamine™ 试剂易于使用,因为它提供了简单快速的方案。只需稀释 Oligofectamine™ 试剂,与寡核苷酸混合,加入到细胞中即可。Oligofectamine™ 试剂需要纳摩尔量的反义寡核苷酸,将所需的有价值的寡核苷酸量减至原来的千分之一。这使其成为高通量应用的理想选择。此外,还已证明 Oligofectamine™ 试剂可用于 siRNA 转染。在 HeLa 细胞中进行 RNAi 敲低实验时,我们建议使用该试剂。有关更多信息,请访问 RNAi 中心。

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。

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。

我应使用何种反应管来配制脂质体:DNA复合物?

聚丙烯、聚苯乙烯或玻璃管可与我们的任何转染产品一起使用而不会有任何问题。

Journal:Assay Drug Dev Technol
PubMed ID:20085456
'The mTORC1 pathway is a central regulator of cell growth, and defective mTORC1 regulation plays a causative role in a variety of human diseases, including cancer, tumor syndromes such as the tuberous sclerosis complex (TSC) and lymphangioleiomyomatosis (LAM), and metabolic diseases such as diabetes and obesity.

Processing of Pro-atrial Natriuretic Peptide by Corin in Cardiac Myocytes.
Authors: Wu Faye; Yan Wei; Pan Junliang; Morser John; Wu Qingyu;
Journal:J Biol Chem
PubMed ID:11884416
'Corin is a type II transmembrane serine protease abundantly expressed in the heart. In a previous study using transfected 293 cells, we showed that corin converted pro-atrial natriuretic peptide (pro-ANP) to atrial natriuretic peptide (ANP), suggesting that corin is likely the pro-ANP convertase. Because other serine proteases such as thrombin ... More

'Endocytosis is a complex process fulfilling many cellular and developmental functions. Understanding how it is regulated and integrated with other cellular processes requires a comprehensive analysis of its molecular constituents and general design principles. Here, we developed a new strategy to phenotypically profile the human genome with respect to transferrin ... More
N-glycans are direct determinants of CFTR folding and stability in secretory and endocytic membrane traffic.

Journal:J Cell Biol
PubMed ID:19307599
'N-glycosylation, a common cotranslational modification, is thought to be critical for plasma membrane expression of glycoproteins by enhancing protein folding, trafficking, and stability through targeting them to the ER folding cycles via lectin-like chaperones. In this study, we show that N-glycans, specifically core glycans, enhance the productive folding and conformational ... More
Disinhibition of neurotrophin-induced dorsal root ganglion cell neurite outgrowth on CNS myelin by siRNA-mediated knockdown of NgR, p75(NTR) and Rho-A.

Journal:Mol Cell Neurosci

'The presence of multiple axon growth inhibitors may partly explain why central nervous system axons are generally incapable of regenerating after injury. Using RNA interference (RNAi) in dorsal root ganglia neurons (DRGN), we demonstrate siRNA-mediated silencing of components of the inhibitory signalling cascade, including p75(NTR), NgR and Rho-A mRNA, of ... More
