Additional Information
Statement
Reference

Drives expression predominantly in the fat body with limited expression in digestive tissues including the hindgut.

(Xu et al., 2008)

ScerGAL4to.PD drives expression in the fat body of the adult head, in the antenna, and in the maxillary palp. Unlike native to expression, ScerGAL4to.PD does not display sex-specific expression.
