C, Co-expression of the HOXs along with the photosensory domain of A. nidulans FphA (PGP) over night at 20°C. PGP was purified via the Strep-tag system and the eluate concentrated (upper panel). The lanes were loaded as follows: negative control before induction (-), 20 h after induction (20 h) crude extract (CE), supernatant (S), pellet (P), flow through (F) and eluate (E). The fractions were analyzed by Western Blot using the Anti-His antibody (lower panel).
