CMMB Tutorial Quiz 1WISH - correct answer Whole-mount Insitu Hybridization -> involves staining whole embryos with complementary RNA probe with label (DIG). Probe is detecting using anti-DIG antibody. *Causes embryos to shrink B-Galactosidase/LacZ reporter assay - correct answer Dna containing enhancer, promoter and reporter injected into embryo creating a transgenic animal. LacZ reporter encodes B-galactosidase enzyme that reacts with substrate addition. Location of staining = location ...
