FAQ of GRAB sensors



Published plasmids are avalible at Addgene and MolecularCloud. For the latest unpublished sensors for ACh, DA, 5-HT, NE, eCB, Ado, ATP etc, please contact yulonglilab2018(a) for information.


Transgenic flies carrying published ACh sensor and dopamine sensor are available at Bloomington Drosophila Stock Center.
