Temperature dependence of trastuzumab stability upon storage for 31 days; the conditions include refrigerated and ambient temperature. Method: 1D-electrophoresis with silver staining; trastuzumab, 1.3–20.5 μg. Molecular weight standards on Lanes A and G for Gels 1, 2 and 4; on Lanes A and H for Gel 3. Gel 1 = control gel (no storage): trastuzumab, 1.3–20.5 μg on Lanes B–F; Gel 2 = samples stored at ambient temperature: trastuzumab 20.5–1.3 μg on Lanes B–F; Gel 3 = samples stored at 4–8 °C vs. ambient temperature: trastuzumab 20.5–1.3 μg on Lanes B–D for refrigerated samples and E–G for ambient temperature; Gel 4 = samples stored at 4–8 °C. Trastuzumab, 20.5–1.3 μg on Lanes B–F.
