What is the expected signal strength for the PTMScan® Control peptides?

We have observed >1E6 peak area for each control peptide when used at the supplied concentration followed by PTMScan and PTMScan HS enrichment, as detected by our LCMS instruments.  However, the limit of detection (LOD) depends on many factors such as the sensitivity of the instrument and the LC gradient that is unique to each user.  Users may adjust the concentration of the supplied peptides as needed to find an appropriate signal strength that has a sufficiently high signal-to-noise ratio for reliable detection.
