Does anyone have any suggestions for preventing mold growth
in protein and peptide/H2O samples? I have been using DDI
H2O, acid-cleaned tubes, and washed caps, but I still get
growth after 2-4 weeks (even at 4 C). I have used NaN3 to
help retard the growth, but I would prefer not to add this
to my samples. Would filtering or working under N2 help?
