• AAV Biosensors - RCaMP Calcium indicator

    Vigene's RCaMP products come ready-to-use, with a choice of promoter with or without Cre inducible (FLEx-ON) expression. AAV8 and AAV9 serotypes of AAV-GCaMP1 are ready to ship. Should you require a different serotype, please contact us.

    RCaMP: Genetically Encoded Calcium Indicators for Multicolor Imaging and 'Read/Write' Optogenetics

    ● RCaMP is a genetically encoded calcium indicator (GECI) which was generated from a fusion of the red fluorescent protein (RFP), calmodulin, and M13, a peptide sequence from myosin light chain kinase.
    Upon the binding of GECI to Ca2+ there is an induction of a change in fluorescence signal. It is this change in signal which allows for measuring the action potentials, and other receptor activation events, that trigger Ca2+ fluxes.

    ● Suitable for simultaneously monitoring activity in two distinct classes of cells.

    ● Applications include use in multicolor functional imaging for drug screening, imaging of cellular activity in cells and organisms already expressing GFP, or imaging with less autofluorescence than green GECIs and dyes.

    Key advantage of RCaMP6

    ● Provides new color channels for single-wavelength functional imaging.

    ● Minimal bleed through into green channel, unlike other biosensors.

    ● Compatible with optogenetic activation/silencing via tools such as channelrhodopsin-2, facilitating “read/write” optogenetics.

    ● T unable affinity under control of various promoters.

    ● Detection using standard optical and nano technologies.
