  1. Different samples of aflibercept and ziv-aflibercept were added to ELISA plates and detected by HRP-conjugated anti-human IgG and H2O2-OPD substrate. Anti-VEGF quantification (mg) was based on a standard curve performed with both drugs. The drugs were initially diluted in saline (1:256,000 for aflibercept; 1:128,000 for ziv-aflibercept). Statistical analysis was performed comparing the samples to the moment condition of each drug. Representative result of three experiments (mean)
  2. The data are expressed as the mean ± SD
