Fig. 2. GFP expression in whole-mount and sectioned transgenic embryos. (A-D)
Examination by brightfield (A,C) or fluorescence (B,D) illumination of a live
whole-mount 72-hour embryo (A,B) and a 72-hour embryo after sectioning and
processing with anti-GFP antibody (C,D). GFP expression is ubiquitous (B,D).
White line in A shows angle of the section. Scale bar: in A, 150 µm for
A,B; in C, 100 µm for C,D.
