This strain was established by Bac transgenic method (construct: Kazuhiro Yamakawa, phD) supported by C.B.S.Nresource (Dr. Kazuto Kobayashi, Dr. Yuchio Yanagawa) in 2014 and maintained at Jikei University School of Medicine. Background: Crlj:WI. Transgene: VGAT (Slc32a1: mouse, Kanamycin registance gene (E. coli), Cre (P1 phage), polyA signal (SV40 virus. Mouse BAC clone: RP23-392-P11). Cre recombinase is expressed under the control of mouse Slc32a1 (VGAT) promoter. This strain is used for GABAergic neuron-specific Cre-Lox site-specific recombination system.
