Additional Information
Statement
Reference

The construct EcollacZCecA1.A12 lacks a 5' region containing Oct sequences, and thus expresses differently than EcollacZCecA1.A10.

(Dantoft et al., 2013)

In embryos, no expression observed in fat body or hemocytes. Embryonic expression assayed after injection with LPS (3-4 hours earlier).
