Biosensors can be used to detect the presence/absence of a particular protein as well as the subcellular location of that protein within the live state of a cell. Fluorescent tags are often desired as a means to visualize the protein of interest within a cell by either fluorescent microscopy or time-lapse video capture. Visualizing live cells without disruption allows researchers to observe cellular conditions in real time.
Lentiviral vector systems are a popular research tool used to introduce gene products into cells. Lentiviral transfection has advantages over non-viral methods such as chemical-based transfection including higher-efficiency transfection of dividing and non-dividing cells, long-term stable expression of the transgene, and low immunogenicity.
EMD Millipore is introducing LentiBrite™ Lentiviral Biosensors, a new suite of pre-packaged lentiviral particles encoding important and foundational proteins of autophagy, apoptosis, and cell structure for visualization under different cell/disease states in live cell and in vitro analysis.
EMD Millipore’s LentiBrite™ α-actinin-RFP lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of autophagy in difficult-to-transfect cell types.
|Background Information||Migration of cells requires engagement of sites of extracellular matrix contact (focal adhesions) with the actin cytoskeleton. Contractile force is further generated when the actin microfilaments develop into stress fibers by bundling in an anti-parallel fashion and recruiting myosin II. A key component of stress fibers is the spectrin-related protein, α-actinin, which directly links actin microfilaments and also couples them to focal adhesions. Imaging of live cells containing α-actinin fused with fluorescent proteins has provided key insights into the dynamic mechanisms of stress fiber assembly and adaptation to strain.
