Immunolocalization of G-protein subunits in PhLP1-deficient rods. Retinal cross-sections from 1-month-old PhLP1+/+Cre+, PhLP1F/+Cre+, and PhLP1F/FCre+ mice were probed with primary antibodies to Gαt1, Gβ1, Gγ1, Gβ4, Gβ5, RGS9, and rhodopsin and detected with fluorescein-conjugated secondary antibodies.
