Description	LentiBrite™ GFP-Vimentin 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™ GFP-Vimentin lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of vimentin IF dynamics in difficult-to-transfect cell types.
Background Information	Intermediate filaments (IFs) are 10 nm diameter cytoskeletal structures that typically form a cage-like structure extending from the nucleus to the plasma membrane. The five families of IF proteins have distinct polymer characteristics and cell type-specific expression patterns. Expression of vimentin, a type-III IF protein, is restricted to mesenchymal cells, and appearance of vimentin in epithelial cancer cells is a hallmark of the epithelial-to-mesenchymal transition. Vimentin assembles into classic long filaments and short filaments termed squiggles. Time-lapse microscopy of live cells expressing GFP-vimentin has revealed the dynamics of vimentin IF maturation, and crosstalk with microtubules and microfilaments. EMD Millipore’s LentiBrite™ GFP-vimentin lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of vimentin IF dynamics in difficult-to-transfect cell types.

Product Information
Components	TagGFP2-Vimentin 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 datasheet. 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, U2OS), while others may require higher MOIs (e.g., human mesenchymal stem cells (HuMSC), human umbilical vein endothelial cells (HUVEC ), 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.
Detection method	Fluorescent
Quality Level	MQ100

Applications
Key Applications	Transfection Immunofluorescence Immunocytochemistry Track single cell and cell population migration (migration assay, cell culture)
Application Notes	Immunocytochemistry Comparison Analysis: Similar to Figure 1 in the datasheet, HeLa cells were plated in a chamber slide and transduced with lentiviral particles at an MOI of 20 for 24 hours. After 24 hours, media was replaced and cells were then further incubated for 48 hours. Immunocytochemical staining (red) of the same fields of view with a monoclonal antibody against Vimentin (Cat No. MAB3400) reveals similar expression patterns to the GFP-protein (green). Hard-to-transfect Cell Types: Primary cell types HUVEC or HuMSC were plated in chamber slides and transduced with lentiviral particles at an MOI of 10 for 24 hours. Confocal Microscopy Imaging: HeLa and U2OS cells were treated as in Figure 2A in the datasheet. Images were obtained by oil immersion confocal fluorescence microscopy. 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.
