Accordingly, the test should only be performed 14 days after stopping acid reducing medication (proton pump inhibitors, PPI) or 28 days after stopping antibiotic treatment. Some clinicians believe that a reservoir of H. pylori in dental plaque can affect the result.

Does urea interfere with SDS digestion?
Any leftovers of SDS will however affect trypsin digestion and can hamper chromatographic separation of peptides and subsequent MS analysis. Urea was shown to be effective in the quantitative removal of SDS (14), but we attempted to streamline the SF-ISD protocol for use with SDC by avoiding urea.
How do you digest protein lysate?
Proteolytic digestion of a complicated protein mixture from an organelle or whole-cell lysate is usually carried out in a dilute solution of a denaturing buffer, such as 1-2 M urea. Urea must be subsequently removed by C18 beads before downstream analysis such as HPLC/MS/MS or complete methylation followed by IMAC isolation of phosphopeptides.
