BacMam 2.0 转导对照可使您体验增强 BacMam 技术的强大和便利性,并方便地读取祖母绿 GFP (emGFP);我们的 Aequorea victoria emGFP 极其明亮且光稳定,该非靶向形式适用于检测转导。在进一步使用更专业的试剂之前,检查 BacMam 2.0 在您的模型中与 GFP 的配合情况如何。

与其他基因转移方法相比,BacMam 2.0 可提供多种优势:

• 高效:对多种哺乳动物细胞系(包括原代细胞、干细胞和神经元细胞)均可实现高效 (>90%) 转导
快速便利:只需将 BacMam 2.0 和细胞一起添加至盖玻片或微量滴定板中,过夜孵育并测定 – 或冷冻储存,以便后续试验直接使用
安全:不会在哺乳动物细胞中复制,无可观察到细胞病变效应,并且适用于生物安全等级 (BSL) 1级处理
灵活:在多重实验或共定位研究中,可共转导一种以上 BacMam 试剂,通过简单调整剂量即可严格控制表达水平

BacMam 技术基于昆虫病毒(杆状病毒),以帮助在哺乳动物细胞中高效递送和表达基因。杆状病毒已经过修饰,以包括表达盒用于哺乳动物细胞中的转基因表达。BacMam 2.0 包含可帮助极大程度提高转导效率和表达水平的元件:用于更有效进入细胞的假型衣壳蛋白和遗传元件(增强 CMV 启动子和土拨鼠转录后调控元件),可提高表达水平。杆状病毒不会在哺乳动物细胞中复制,因此具有出色的安全性特征,并且对细胞无细胞病变效应。

先前与该技术不兼容(神经元细胞、T 细胞)或仅转导不良(一些干细胞、CHO)的细胞类型现在能够以简单的一步法进行定量转导。

我们提供多种基于 BacMam 的试剂,包括 Cellular Lights™ 细胞标记试剂、Premo™ 生物传感器、离子通道药物靶标、通路分析试剂盒等。如要了解关于这些产品的更多信息,请访问 www.invitrogen.com ⁄bacmam

现在,另一种基于 BacMam 2.0 的试剂是我们授权的 Premo™ 自噬传感器,用于活细胞自噬研究。

常见问题解答 (FAQ)

我使用你们的CellLight BacMam 试剂对我的细胞器进行荧光蛋白标记,但是标记效果不佳。我该如何加以改善?

首先,确定你们的细胞是哺乳动物且非血源性细胞。如果细胞转导效率不佳(例如只有少数细胞被标记或是标记荧光很暗),先试着增加每个细胞的微粒数。接下来试着使用BacMam Enhancer Solution。但是,如果你们的细胞显示标记而标记定位似乎太过普遍或是无处不在,那么你们应该降低每个细胞的微粒数。该手册给出了计算每个细胞的微粒数的指南和公式。

How can I increase the transduction efficiency with the BacMam 2.0 reagents such as the the CellLight and Premo products?

Try varying particle-to-cell ratio (PPC), incubation volume, temperature and, cell density (if adherent cells are transduced). For adherent cells, we recommend a confluence of about 70%. Following the PPC, adjusting the volume is the next best parameter to change to optimize protein expression. If that doesn't work, you can also use the BacMam Enhancer Kit (Cat. No. B10107).

Is there any way to preserve the CellLights labeling beyond 5 days?

Cells transduced with the CellLights reagents can be stored frozen for several months after transduction, without loss of expression.

Are the CellLights products toxic to cells?

If the viral particles are used at the level we recommend, they are very well tolerated by cells.

For how long will the CellLights products label my cells?

The BacMam 2.0 CellLights typically express for 5 days after transduction.

The recombinant baculovirus/insect cell system was firmly established as a leading method for recombinant protein production when a new potential use for these viruses was revealed in 1995. It was reported that engineered recombinant baculoviruses could deliver functional expression cassettes to mammalian cell types; a system which has come to ... More

This paper describes the use of the baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) as a vector for gene delivery into mammalian cells. A modified AcMNPV virus was prepared that carried the Escherichia coli lacZ reporter gene under control of the Rous sarcoma virus promoter and mammalian RNA processing ... More
