• AAV Biosensors

    Vigene's AAV Biosensor products come as ready-to-use AAV vectors. The vectors are genetically encoded with your chosen biosensor, either calcium or glutamate sensors. These products are ready for in vivo injection. These biosensors are made possible through a world-wide license from Janelia Research Campus, HHMI.

    What are Biosensors?

    Biosensors are genetically engineered fluorescent proteins (FP) attached to an additional protein sequence which makes them sensitive to small biomolecules or other physiological intracellular processes (e.g. Ca2+). These biosensors are introduced into cells, tissues or organisms to detect changes by fluorescence microscopy intensity or spectrum change. Many biosensors permit long-term imaging and can be engineered to specifically target cellular compartments or organelles. Additionally, biosensors permit signaling pathway exploration or allow for the measurement of a biomolecule. They do all this while principally preserving both spatial as well as temporal cellular processes.

    Fluorescent Protein Biosensors diagram - How they work

    Schematic representation of FP-based biosensor. The fusion of an FP such as GFP (green) to a specific binding domain, shown in gray, can be used to report on the production of certain signaling molecules. Ca2+ sensors consists of a molecular switch that contains calmodulin (CaM) and M13 inserted into a circularly permuted GFP, shown in green, in which the native N- and C-termini of GFP are linked together, and new termini are generated from within the core Β-barrel structure of GFP; the addition of Ca2+ causes CaM to bind to M13, which leads to increased GFP fluorescence.

    How do you choose an AAV biosensor?

    ● Decide which biosensor is most suitable for your research question - calcium or glutamate; for example for GCaMP6, decide whether you need GCaMP s or m, f.

    ● Decide whether you would like to include FLEX Learn more.

    ● Choose a promoter (universal promoter - CAG, or tissue specificneuron specific-synapsin promoter).

    ● Choose the AAV vector serotype (AAV1-9; AAV8 and AAV9 are ready-to-ship).

    What to do after receiving your biosensors

    All AAV-biosensors come in ready-to-inject and ready-to-transduce format of AAV vectors. Upon receipt, please store them in -80C.
