This invention describes the development of a monoclonal antibody that is highly useful for examining the expression of engrailed and invected gene products in Drosophila and a number of different arthopods, annelids, and chordates. The epitope fothe the antibody has been localized to residues 38-58 of the homeodomain. Engrailed class proteins play several fundamental roles in embryo patterning and this antibody is useful for examining the segmentation from the cellular blastoderm stage onward.

Antibody recognizes engrailed products in Drosophila, grasshopper, crayfish, lobster, zebrafish, chicken, and Xenopus.
Can be used to rapidly study gene expression of engrailed proteins in a variety of organisms.
