      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™ PSD-95-GFP lentiviral particles provide bright fluorescence and precise localization to enable live cell analysis of PSD dynamics in neuronal cells.
      Background InformationThe postsynaptic side of an excitatory synapse contains an electron- and protein-dense region, the postsynaptic density (PSD), that positions neurotransmitters adjacent to sites of presynaptic neurotransmitter release, and also concentrates signaling molecules. MAGUKs (membrane-associated guanylate kinases) serve both as central organizers of the PSD and as signaling molecules. One such MAGUK, PSD-95, is associated with the dendritic spines of mature synapses, and is relatively immobile compared to other MAGUKs. PSD-95 fused to fluorescent proteins has been employed to quantify turnover and mobility of PSD-95.

      Components
      • TagPSD95-GFP2 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 neurons to achieve high transduction efficiency and signal intensity are in the range of 20-40. For this target, some neuronal cell types may require higher or lower MOIs.
        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.

      • Immunocytochemistry
      • Track single cell and cell population migration (migration assay, cell culture)
      Application NotesFluorescence microscopy imaging:
      Primary rat hippocampal neuron cells were plated in a poly-D-lysine coated chambered cover glass for 5 days and transduced with lentiviral particles at an MOI of 20 for 24 hours. After media replacement and 2 weeks further incubation, cells were imaged live by oil immersion wide-field fluorescence microscopy. The PSD95-GFP displays a dotted distribution along the neurites.

      Immunocytochemistry Comparison:
      Rat hippocampal neuron 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 2 weeks. Immunocytochemical staining (red) of the same fields of view with a monoclonal antibody against PSD95 (Cat No. MAB1596) reveals similar expression patterns to the GFP-protein (green).

      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.

      Storage and Shipping Information
      Storage ConditionsStorage and Handling
      Lentivirus is stable for at least 4 months from date of receipt when stored at -80°C. After first thaw, place immediately on ice and freeze in working aliquots at -80°C. Frozen aliquots may be stored for at least 2 months. Further freeze/thaws may result in decreased virus titer and transduction efficiency.

      IMPORTANT SAFETY NOTE
      Replication-defective lentiviral vectors, such as the 3rd Generation vector provided in this product, are not known to cause any diseases in humans or animals. However, lentiviruses can integrate into the host cell genome and thus pose some risk of insertional mutagenesis. Material is a Risk Group 2 and should be handled under BSL2 controls. A detailed discussion of biosafety of lentiviral vectors is provided in Pauwels, K. et al. (2009). State-of-the-art lentiviral vectors for research use: Risk assessment and biosafety recommendations.
