• AAV Biosensors

    Vigene's AAV biosensors come ready-to-use and our product range includes a variety of calcium and glutamate biosensors made possible through a world-wide license from Janelia Research Campus, HHMI. Please see our AAV Biosensors Handbook for more information.

    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.
