Characterization of the PRIMVAC vaccine formulation. Stability of PRIMVAC in presence of Alhydrogel® (AlOH) or GLA-SE was assessed at different time points by SDS-PAGE followed by Coomassie Blue staining and western blotting using an anti-DBL1x antibody for specific detection of the protein of interest. All blots derive from the same experiment and were processed in parallel. DBL1x-2x drug substance (DS; engineering batch) and DBL1x-2x drug product (DP; released batch) were used as protein integrity controls.
