Miltenyi货号130-111-163病毒感染增强剂Vectofusin-1上海睿安生物19121878899

Vectofusin-1是一种合成的、无细胞毒性的阳离子多肽,能够提高病毒对造血干细胞以及悬浮细胞的感染效率。方便使用,应用时无需提前包被培养板。
使用逆转录病毒载体将基因转移到悬浮细胞(例如T细胞或造血干细胞)中,可应用于多种疾病治疗,包括单基因疾病,传染性疾病和癌症。使用逆转录病毒载体对悬浮细胞进行病毒转导通常效率低下,需要使用转导增强子。Vectofusin-1是一种完全合成的无毒阳离子的合成肽,具有病毒转导增强功能,可通过少量逆转录病毒载体实现更高的转导水平。当添加到培养基中时,Vectofusin-1会促进几种逆转录病毒假型进入靶细胞。
|
优点: |
-Vectofusin-1更容易使用,因为它可以直接添加到转染培养基中,而Retronectin需要一个包被步骤,这是很难标准化的,容易导致与细胞有关的添加剂数量不精确,并增加病毒转导的步骤;-将CD34 HSCs与Retronectin包被的培养皿表面结合可能会降低在培养袋中转导后获得的细胞的产量,这是一种 Vectofusin-1等可溶性因子不容易出现的副作用;-Retronetin包被培养皿表面诱导的细胞粘附可能加速干细胞亚群的分化,而这一步骤在悬浮培养中可能会得到更好的控制;-Vectofusin-1是一种相对较小的由26个氨基酸组成的合成肽,它是水溶性的,并根据体内外临床应用的良好反应制造、合成和纯化。 |

组成成分:▪Vectofusin-1:多肽,1mg
Specifications for Vectofusin®-1
Overview
Vectofusin-1 is a non-toxic histidin-rich amphipathic peptide which exerts as viral transduction enhancer. Unlike recombinant fibronectin, it does not have to be precoated on cell culture surfaces, thus streamlining the transduction process.
Detailed product information
Background information
Gene transfer into suspension cells such as T cells or hematopoietic stem cells using retroviral vectors has several therapeutic applications ranging from monogenic diseases, infectious diseases, and cancer. Viral transduction of suspension cells using retroviral vectors is often inefficient and requires the use of transduction enhancers. Vectofusin-1 is a fully synthetic non-toxic cationic amphipathic peptide with viral transduction enhancing capacity, enabling higher transduction levels with low amounts of retroviral vector. Vectofusin-1 promotes the entry of several retroviral pseudo-types into target cells when added to the culture medium.
Applications
Enhancement of lentiviral transduction
Enhancement of retroviral transduction
