Fig. 2From: Pre-clinical study of IRDye800CW-nimotuzumab formulation, stability, pharmacokinetics, and safetyLong term stability of IRDye800CW-nimotuzumab. Four batches of IRDye800CW-nimotzumab were stored at − 80 °C and the stability was analyzed by microcapillary electrophoresis to assess purity over time. The line is the best fit and the shaded area is the 95% confidence intervalBack to article page
