The following information accompanied stocks donated to the Bloomington Stock Center by Rachel Wilson, Harvard University.
UAS-driven cytosolic mStayGold and membrane-targeted mStayGold. Bright, photostable GFP reagent that is useful for live imaging, particularly during development. When membrane tagged it is superior to  mCD8::GFP  for brightness, which is great for patch-clamp of 'dim' driver lines.

UAS-driven cytosolic mNeonGreen. Reagent is super-resolution compatible and seems to work for live-cell super resolution (e.g. STED microscopy).

mCyRFP3-Kir fusions: Kir2.1 fused to a cyan-excitable red-fluorescent protein (mCyRFP3) that is visible during standard 2-photon imaging without extra hardware. All were validated by patch clamp and functional imaging.

mCyRFP3-CsChrimson fusions: optogenetic stock with CsChrimson fused to mCyRFP3 that is visible during standard 2-photon imaging. All validated by patch clamp/2-photon for light-activation, and wide-field/2-photon for fluorophore localization and brightness.

mCyRFP3-GCaMP fusions and bicistronic expression constructs: fused GCaMP7 and GCaMP8 variants with mCyRFP3 for ratiometric imaging. Also created bicistronic constructs for experiments that require the expression of both constructs separately. All have been validated for expression and function, in some cases with a large number of drivers.

Syt1-mCyRFP3-GCaMP double fusions and bicistronic expression constructs: synapse-targeted calcium indicator with mCyRFP3 fluorophore. Also created bicistronic constructs for experiments that require the expression of both constructs separately. These have been validated by functional imaging.
