It has already been shown that there can be lot-to-lot variation of VP PTMs during production , therefore, having a QC-ready platform that can detect such differences is of the utmost importance for product quality control. Once created, both, the rapid identity testing method and the PTM monitoring method can be easily applied to sample analysis in Chromeleon without the need to rerun samples. A sample selected during rapid identity testing is simply reprocessed using the PTM monitoring method. Reports detailing the results of either method can then be generated within Chromeleon for necessary QC documentation (See supplementary information for examples of reports generated).
