Microbial colonies on metal MALDI plate falls off in dry vacuum environment of MS instrument.. Any suggestion for fix?

23 September 2020 0 7K Report

I am trying to analyze E. coli colonies for fatty acid production by using MALDI-ToF-MS. Microbial colonies attached to MALDI plate fall off within the vacuum environment of MALDI-MS device.. Do you have any suggestion for making colonies sticky? ?

Let me know.. Thanks.
