Protecting LPL against freeze/thaw and lyophilization‐induced inactivation. Buffered LPL (0.28 mg/L) was formulated with various concentrations of additives before flash freezing. Freeze/thawe samples were stored at −80°C. Other samples were lyophilized. Normalized activity was determined by comparison to an LPL solution stored at −80°C without freeze/thaw stress. Curves were added as a visual guide but have no theoretical significance.
