How long would the OMVs be stable at -80 °C vs. 4°C? and what is the best way to test for OMV integrity you would recommend (TEM? protein concentration?). Thank you.

According to our previous data on the stability of OMVs in different conditions, both -80 and 4 C showed similar stability. But I would recommend -80 C for long storage. To check the OMV integrity, I recommend analyzing the size of OMV and shape using dynamic light scattering or TEM imaging.
