GCaMP6s expression and fluorescencein Tg[?actin2:GCaMP6s]stl351/stl351 and Tg[ubi:GCaMP6s]stl352/stl352 transgenic zebrafish during early embryogenesis. (A) Schematics of the Tol2[?actin2:GCaMP6s] or Tol2[ubi:GCaMP6s] constructs. (B) GCaMP6s fluorescent confocal microscope images in Tg[?actin2:GCaMP6s]stl351/stl351 and Tg[ubi:GCaMP6s]stl352/stl352 embryos at several developmental stages. a, a?, d, d?, lateral view; b, b?, c, c?, animal pole view. Asterisks indicate the yolk, and arrowheads point to the blastodisc in a, a?. Arrows point to the heart in d, d?. (C-D)RT-PCR and qRT-PCR analyses of GCaMP6s RNA expression levels in Tg[?actin2:GCaMP6s]stl351/stl351 and Tg[ubi:GCaMP6s]stl352/stl352 embryos in the course of embryogenesis. The qRT-PCR results were normalized to ?-actin. Error bars represent standard deviation; N=3.
