zebrafish hoxa2b (previous name hox a2) in unknown vector for making antisense probe. from Moens lab. Prince, V.E., Moens, C.B., Kimmel, C.B., and Ho, R.K. (1998) Zebrafish hox genes: expression in the hindbrain region of wild-type and mutants of the segmentation gene valentino. Development 125:393-406.
expressed in r2 and r3 from 1 somite to 5 somite stage. later spreads to r4 and r5, but levels stay higher in more anterior rhombomeres. also in neural crest migrating in 2nd and 3rd branchial arch at the 20 somite stage.
for antisense: Asp718, T3
