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-LC3-G120A mutant lentiviral particles serve as a negative control alongside GFP-LC3 wild-type (catalog # 17-10193) for live cell analysis of autophagy.

Background Information	Autophagy, a degradative pathway that provides recycled nutrients to cells under stress, plays both protective and deleterious roles in many diseases, including cancer, neurodegeneration, and infections. Members of the LC3 family play a key role in the maturation of the autophagosome, the central organelle of autophagy. LC3 precursors, diffusely distributed in the cytosol, are proteolytically processed to form LC3-I. Upon initiation of autophagy, the C-terminal glycine is modified by addition of a phosphatidylethanolamine (PE) to form LC3-II, which translocates rapidly to nascent autophagosomes in a punctate distribution. DNA constructs encoding fluorescent proteins fused to LC3 are widely employed for introduction into cells for monitoring autophagosome formation by fluorescence microscopy. A mutant form of LC3 with the C-terminal glycine changed to alanine (LC3-G120A) is unable to accept the PE modification and fails to translocate to the autophagosome upon induction of autophagy. EMD Millipore’s LentiBrite™ GFP-LC3-G120A lentiviral particles serve as a negative control alongside GFP-LC3 wild-type (catalog # 17-10193) for live cell analysis of autophagy.

Product Information
Components	TagGFP2-LC3-G120A (Mutant) 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 lot specific “Viral Titer” in the product specifications of 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., HeLa, human mesenchymal stem cells (HuMSC)), while others may require higher MOIs (e.g., HT-1080, human umbilical vein endothelial cells (HUVEC), U2OS). 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.

Key Applications	Transfection Immunofluorescence Immunocytochemistry
Application Notes	Fluorescence Microscopy Imaging: (See Figure 1 in datasheet) HT-1080 cells were plated in a chamber slide and transduced with lentiviral particles at an MOI of 20 for 24 hours. After media replacement and 48 hours further incubation, cells were either lleft in complete media or incubated for 4 hours in EBSS containing a lysosome inhibitor, to induce autophagy and inhibit lysosomal degradation of autophagosomes. Cells were fixed with formaldehyde and mounted. Images were obtained by oil immersion wide-field fluorescence microscopy. The GFP-LC3 Control Mutant displays a diffuse nuclear and cytosolic distribution in both fed and starved autophagic cells (i.e., no translocation to a punctate cytoplasmic distribution as characteristic of wild-type LC3). Immunocytochemistry Comparison and Inhibitor Analysis: (See Figure 2 in datasheet) Similar to Figure 1 conditions (see datasheet), HeLa cells were plated in a chamber slide and transduced with lentiviral particles at an MOI of 20 for 24 hours. After media replacement and 48 hours further incubation, cells were either left in complete media, incubated for 4 hours in EBSS containing a lysosome inhibitor to induce autophagy and inhibit lysosomal degradation, or incubated as in, with the addition of 5 mM 3-methyladenine (3-MA) as an inhibitor of autophagy. 3-MA does not affect GFP-LC3 Control Mutant localization. Immunocytochemical staining (red) of the same fields of view with a monoclonal antibody against LC3A reveals a similar expression pattern to the mutant protein (green) under fed conditions. Immunostaining of starved cells displays the punctate distribution of endogenous wild-type LC3, while signal following 3-MA treatment is diminished. Hard-to-transfect Cell Types: (See Figure 3 in datasheet) Primary cell types HUVEC or HuMSC were plated in chamber slides and transduced with lentiviral particles at an MOI of 40 for 24 hours. Subsequent treatments for cells left in complete media or cells incubated in EBSS with lysosome inhibitor, were performed as in Figures 1A and 1B (see datasheet). 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.
