Fig. 6. (A) Rhabdomere structure in rdgA1 is rescued to equivalent levels by su(1) and InaD1. (B) Western blot using an antiserum against INAD showing wild-type INAD protein missing from head extracts of su(1) and su(100) but not su(40). The established protein-null mutant InaD1 is used as a negative control to identify the INAD band. Control panel shows the same blot detecting syntaxin as a loading control to show equivalent levels of protein in all samples.
