Pregnancy has been traditionally defined as the period during which developing embryos are incubated in the body after egg-sperm union. Despite strong similarities between viviparity in mammals, researchers have historically been reluctant to use the term "pregnancy" for non-mammals because of the highly developed form of viviparity in eutherians. Recent research into physiological, morphological and genetic changes associated with fish reproduction provide evi… Web3.3 Single FISH on Drosophila Embryos 3.3.1 Postfixation, Hybridization, and Posthybridization Washes. Hybridizations can be performed in 1.5/0.5-mL microfuge tubes (50 µL settled embryos) or 0.2-mL PCR plates (10 µL settled embryos/well). The latter are particularly well suited for optimizing experimental conditions (i.e., antibody ...
