产品应用：Ai94(TITL-GCaMP6s)-D;CaMK2a-tTA (or Ai94D;CaMK2a-tTA) mice have a Cre/Tet-dependent, fluorescent calcium indicator GCaMP6s inserted into the Igs7 locus (TIGRE; an intergenic region on mouse chromosome 9 that allows reporter expression to be tightly regulated), as well as a transgene directing tetracycline-controlled transactivator protein (tTA) expression in forebrain neurons. After removal of the floxed-STOP cassette by Cre recombinase, resulting mice have doxycycline-inducible/reversible expression of GCaMP6 slow variant calcium indicator (GCaMP6s; an ultrasensitive detector of single neuronal action potentials with slower decay and response kinetics). Following subsequent calcium binding (such as neuronal activation), increased EGFP fluorescence is observed in those cells.
