Western blot analysis of VEGF and PEDF expressed in idiopathic epiretinal membranes and proliferative diabetic retinopathy membranes.
(A) The extracted proteins were used in immunoblotting to detect VEGF and PEDF. GAPDH was used as protein loading control. Blot is representative. (B) Relative levels of VEGF and PEDF from 3 independent experiments were quantified by measuring band intensity with Image J software. Data were normalized by comparing to the control. *P< 0.01.
