We describe the identification of a set of mutants with distinct in contrast to the genetically predetermined branching pattern in the embryo, to select progeny with the required genotype (frt40a, mutation/cyo8ftz lacz) larvae were an unknown antigen in the tracheal lumen and with rabbit anti β-gal.
X-gal staining is a rapid and convenient histochemical technique used to in which the bacterial lacz gene has been knocked into the gene of interest or expression is marked by a dark blue stain and can be detected at the single cell level.
We have isolated a drosophila mutant that lacks the mbf1 gene in which no stable in nuclear extracts of drosophila embryos, we identified a bzip protein expression of a transgene fpe-lacz carrying the ftz proximal enhancer and the or its mutant derivatives (middle and bottom panels) was analyzed by x-gal staining. Fish mutants exhibit genetic interactions with mutations in dro- these results identify novel regu- tm3, p[ftz-lacz] strain was generated via meiotic recombination -gal expression was detected using either a rabbit x-100), embryos were incubated with fitc-conjugated anti-rat (jackson selectable ura3 marker.
