描述
产品目录编号	17-10387
商名	Chemicon LentiBrite
描述	LentiBrite™ GFP Control Lentiviral Biosensor
概述	*Read our application note in Nature Methods!* 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 Control lentiviral particles provide bright fluorescence to enable live-cell analysis in difficult-to-transfect cell types.
背景信息	The use of genetically encoded fluorescent proteins has revolutionized cell biology by enabling real-time imaging of cells and subcellular structures. A diverse palette of fluorescent proteins is available, but these proteins vary in their suitability for live-cell imaging. EMD Millipore’s LentiBriteTM GFP Control Lentiviral Biosensor employs TagGFP2, the improved variant of the Aequorea macrodactyla GFP-like protein. TagGFP2 exhibits bright green fluorescence comparable to that of EGFP, with excitation/emission maxima at 483 and 506 nm, respectively. TagGFP2 is specially optimized for expression at 37°C and is therefore well-suited for use in mammalian cells. EMD Millipore’s LentiBrite™ GFP Control lentiviral particles provide bright fluorescence to enable live-cell analysis in difficult-to-transfect cell types.

产品信息
部件	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, HeLa, U2OS, human mesenchymal stem cells (HuMSC)), while others may require higher MOIs (e.g., human umbilical vein endothelial cells (HUVEC)). 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. TagGFP2 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)

应用
主要应用	Immunocytochemistry
应用说明	Fluorescence Microscopy Imaging: (See Figure 1 in datasheet) HeLa 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 GFP displays a uniform green fluorescent distribution in the cells. Immunocytochemistry Comparison: (See Figure 2 in datasheet) Similar to Figure 1 (see datasheet), U2OS cells were plated in a chamber slide and transduced with lentiviral particles at an MOI of 40 for 24 hours. After 24 hours, media was replaced and cells were then further incubated for 48 hours. 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. Additional cell type: (See Figure 4 in datasheet) Primary Rat Cortical Neuron cells were treated as in Figure 1 (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.
