LifeAct, a 17-amino acid peptide, is derived from a protein from Saccharomyces cerevisiae. LifeAct stains filamentous actin (F-actin) structures in living or fixed eukaryotic cells and tissues.
Please find detailed information about LifeAct here.
LifeAct-Adenoviral Vectors are used for difficult-to-transfect cells or when up to 100 % transgene expressing cells are needed. For many cell lines, the CMV (cytomegalovirus) promoter is the best choice as it leads to strong expression of LifeAct.
After the transduction of cells with rAV-LifeAct, F-actin is visualized using the fluorescence markers TagGFP2 or TagRFP**. With this method, transduction efficiencies up to 100% can be attained, even in difficult-to-transfect cell types like primary cells (e.g., neuronal cells). This virus can be used for transient protein expression. To generate stable cell lines, please refer to our LifeAct Lentivirus products.
LifeAct plasmids may be used in many cell types when a transient or stable expression of LifeAct is needed. In this case, it is also possible to choose between the two promoters mentioned before.
In addition, different stable cell lines are available, which help facilitate daily lab life. You can immediately start performing experiments without the time-consuming and laborious generation of stable cell lines, while still assuring high-quality standards.
