Description	LentiBrite™ Paxillin-RFP Lentiviral Biosensor
Overview	*Read our application note in Nature Methods!* http://www.nature.com/app_notes/nmeth/2012/121007/pdf/an8620.pdf (Click Here!) Learn more about the advantages of our LentiBrite Lentiviral Biosensors! Click Here 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. Pre-packaged, fluorescently-tagged with GFP & RFP Higher efficiency transfection as compared to traditional chemical-based and other non-viral-based transfection methods Ability to transfect dividing, non-dividing, and difficult-to-transfect cell types, such as primary cells or stem cells Non-disruptive towards cellular function EMD Millipore’s LentiBrite™ Paxillin-RFP lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of focal adhesion dynamics in difficult-to-transfect cell types.
Background Information	Adherent cells maintain contact with the extracellular substratum by means of focal adhesions, comprising transmembrane matrix receptors (integrins) linked on their cytoplasmic side to a complex of signaling and structural proteins, which are in turn linked to the cytoskeleton. Paxillin, one of the first proteins recruited to nascent adhesions, serves as a scaffolding protein for kinases (Src, FAK), GTP exchange factors and other structural proteins, and plays a key role in assembly and disassembly of focal adhesions. Focal adhesions are highly dynamic structures that assemble at the leading edge of the migrating cell and disassemble at the trailing edge, and fusions between paxillin and fluorescent proteins have been widely employed for analysis of focal adhesion dynamics in live cells. EMD Millipore’s LentiBrite™ Paxillin-RFP lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of focal adhesion dynamics in difficult-to-transfect cell types.

Product Information
Components	Paxillin-TagRFP Lentivirus: One vial containing 25 µL of lentiviral particles at a minimum of 3 x 10E8 infectious units (IFU) per mL. For lot-specific titer information, please see “Viral Titer” in the product box above. Promoter EF-1 (Elongation Factor-1) Multiplicty of Infection (MOI) MOI = Ratio of # of infectious lentiviral particles (IFU) to # of cells being infected. Typical MOI values for high transduction efficiency and signal intensity are in the range of 20-40. For this target, some cell types may require lower MOIs (e.g., HT-1080, human mesenchymal stem cells (HuMSC)), while others may require higher MOIs (e.g., human umbilical vein endothelial cells (HUVEC), U2OS, HeLa). NOTE: MOI should be titrated and optimized by the end user for each cell type and lentiviral target to achieve desired transduction efficiency and signal intensity.

Applications
Key Applications	Transfection Immunofluorescence Immunocytochemistry
Application Notes	Fluorescence microscopy imaging: (See Figure 1 in datasheet) REF52 cells were plated in a chamber slide and transduced with lentiviral particles at an MOI of 40 for 24 hours. After media replacement and 48 hours further incubation, cells were fixed with formaldehyde and mounted. Images were obtained by oil immersion wide-field fluorescence microscopy. The paxillin-RFP displays a punctuate distribution at focal adhesions in cells. Immunocytochemistry comparison and inhibitor analysis: (See Figure 2 in datasheet) Similar to Figure 1 (see datasheet), HeLa cells were plated in a chamber slide and transduced with lentiviral particles at an MOI of 5 for 24 hours. After 24 hours, media was replaced and cells were then further incubated for 48 hours. Immunocytochemical staining (green) of the same fields of view with a monoclonal antibody against paxillin (Cat No. 05-417) reveals similar expression patterns to the protein-RFP (red). Additional cell types: (See Figure 3 in datasheet) U2OS and HT1080 cells were treated as in Figure 1 (see datasheet) at an MOI of 5 and 10, respectively, for 24 hours. Hard-to-transfect cell types: (See Figure 4 in datasheet) Primary cell type HUVEC and Human mesenchymal stem cells (HuMSC) were plated in chamber slides and transduced with lentiviral particles at an MOI of 5 and 20, repectively, for 24 hours. For optimal fluorescent visualization, it is recommended to analyze the target expression level within 24-48 hrs after transfection/infection for optimal live cell analysis, as fluorescent intensity may dim over time, especially in difficult-to-transfect cell lines. Infected cells may be frozen down after successful transfection/infection and thawed in culture to retain positive fluorescent expression beyond 24-48 hrs. Length and intensity of fluorescent expression varies between cell lines. Higher MOIs may be required for difficult-to-transfect cell lines.
