Figure 1. Loss of IR expression in the RPE of RPEIRKO mice.
(A) RPE/choroid flatmounts were prepared from non-diabetic IR flox and RPEIRKO mice at 6 weeks of age. Tissue was stained with mouse anti-Cre antibody (green), rabbit anti-IRβ antibody (red) and counterstained with DAPI. Scale bar = 500μm. (B) RPE lysates were prepared from IR flox, Best1-Cre and RPEIRKO mice. Western blotting was performed using anti-IRβ, anti-actin (top) and anti-cre recombinase (bottom) antibodies.
