engrailed + en-lacZ
Expression: engrailed (en) is expressed in NB 1-2, the median NB, and all
row 6 and 7 neuroblasts from the time of their formation through S5.
Check out the map for details.
At stage 16 en is found in a subset of neurons both in the anterior and
posterior compartments (see
Cui and Doe, (1992) for the names of neurons).
Other remarks: The 4D9 anti-invected antibody can be used to follow en
expression. It makes a good landmark for positioning and double-labels.
The Flybase reference for en might be useful.
