Figure 4. Representative western blot analysis for GFAP on two XLPRA1-affected retinas (S1 and S2, 16 weeks) versus the age-matched healthy retina (16 weeks). Quantification of proteins on western blot performed with Li-COR Odyssey software showed upregulation of GFAP in S1 and S2 retinas of 2.3 and 2.5 times, respectively.
