Figure 5From: Identification and characterization of a POU transcription factor in the cotton bollworm, Helicoverpa armigeraDetection of Har-POU binding activity by electrophoresis mobility shift assay. (A) Har-POU binds with probes SA, S1, and H1. (B) 40-fold of cold H1 specifically competes the biding of Har-POU and H1. The sequences of the probes SA, S1, and H1 are described in materials and methods. P, probe; POU, Har-POU protein expressed in vitro; com, cold H1 as a competitor.Back to article page
