Immunocytochemistry Reveals Rhabdomeral Localization of INAD Phosphorylated at Thr170/Ser174.

<p>Tangential cryosections from the eyes of light- or dark-adapted wild type flies were probed with a pan-specific α-INAD antibody or with α-pThr170/pSer174 (green) and with phalloidin that specifically labels the rhabdomeres (red). Colocalizing signals from both channels appear yellow in the merged panels. Scale bar, 10 μm; α-pAB, phosphospecific antibody.
