Fig 5. CE-SDS electropherograms of anti-BoNT 9ABE under non-reducing and reducing conditions after storage at 5°C (red), 30°C (black) and 50°C (blue) for six months.

A. Non-reducing, stored lyophilized. B. Non-reducing, stored as liquid. C. Reducing, stored lyophilized. D. Reducing, stored as liquid. The peak at approximately 11.5 minutes is an internal standard (STD) of 10 kDa in panels A, C, D.
