Figure 10. Analysis of GFP expression driven by Caenorhabditis hexosaminidase promoters. Fluorescence microscopy of worms transformed with various hex::gfp constructs indicates that there is differential expression driven by the putative promoter regions of the
hex-1, -2, -3, -4, and -5 genes. Pairs of confocal and fluorescent micrographs for
hex-1::gfp (whole worm (A) and tail coelomocyte (B)),
hex-2::gfp (head region (C), vulval region lateral view (D), vulval region top view (E), and tail region (F)),
hex-3::gfp (L1 larvae (G)),
hex-4::gfp (L1 larvae (H) and embryos (I)) and
hex-5::gfp (embryo (J) and whole worm (K)) transgenic worms are shown.
