ibidi 活細(xì)胞骨架染料LifeAct Adenoviral Vectors

LifeAct是一個(gè)來源于酵母菌蛋白的17個(gè)氨基酸組成的多肽,可以對(duì)活細(xì)胞或固定細(xì)胞的F-Actin染色。
與GFP-actin和其他的actin綁定蛋白相比,LifeAct的優(yōu)勢(shì)在于無論體內(nèi)還是體外都不影響actin動(dòng)力、
作為一個(gè)新型actin marker,它獨(dú)特的特性使之成為今天好用的F-Actin marker。
ibidi熒光標(biāo)記rAV-LifeAct轉(zhuǎn)導(dǎo)細(xì)胞之后,通過熒光marker tagGFP2或TagRFP使F-actin可視化。
通過病毒載體轉(zhuǎn)導(dǎo),對(duì)于一些難轉(zhuǎn)染的細(xì)胞,如原代細(xì)胞和神經(jīng)元細(xì)胞,效率也可以達(dá)到99%。

易必迪 ibidi 細(xì)胞骨架 HT-1080 LifeAct-TagGFP2 Stable Cell Line
貨 號(hào):40101/40101
A stable LifeAct-TagGFP2 expressing human fibrosarcoma cell line
Long-term actin visualization - 25 passages guaranteed
Characteristics proven to be identical to the parental HT-1080 cell line
LifeAct technology guarantees no interference with cytoskeletal dynamics
易必迪 ibidi 細(xì)胞骨架染料 LifeAct Adenoviral Vectors Applications:
Live cell imaging of cytoskeletal organization and dynamics
Functional cell-based assays, such as chemotaxis and migration
Usable as a characterized control in your experiments
To create the stable LifeAct-TagGFP2 expressing cell line, human fibrosarcoma cells were stably transfected with a plasmid coding for
TagGFP2-labeled LifeAct .
The HT-1080 LifeAct-TagGFP2 cells present highly dynamic filamentous actin. As a result of stable LifeAct expression, perfect visualization
of filamentous actin with very low background fluorescence is achieved without any interference to cellular dynamics.
Moreover, full characterization of the cells revealed that they displayed identical behavior to wild type (wt) cells.
Due to the cell line’s fast growth and the absence of contact inhibition, it constitutes an ideal tumor model.
These characteristics combined with bright and specific F-actin staining lead to a powerful tool with versatile applications in live cell imaging and
high-content approaches.
