floating head (flh = znot1) full-length in SK- for antisense probes. cloned and WMISH by Talbot, 1995
Flh is expressed in the whole marginal zone of the late blastula and becomes restricted to the shield in the early gastrula. At bud stage the notochord strongly and the midline of the neural plate weakly express flh. As segmentation begins, expression is lost from anterior areas and at 9-10 somites, the posterior notochord and neural keel express; in addition, expression is found in the polster and the dorsal diencephalon
for antisense: EcoRI, T7
