Protein quantitation with confidence




The protein quantification workflow highlighted in this webinar will enable scientists in learning about the benefits of QTRAP that can be used to overcome an analytical challenge faced by all triple quadrupole instruments. Although the accurate full scan analytical functions of HRMS has been used for quantification of biotherapeutics, use of QTRAP offers some great advantages in sensitivity and selectivity. This webinar will also highlight results from one of our recently concluded studies on DMS-MIM approach for a few peptides. These results show that the QTRAP 6500 system performed equally well when compared to that of a high end HRMS system. Although additional data is needed to confirm the observation, QTRAP systems can be used efficiently for performing quantification of peptides that are otherwise difficult to address by standard MRM methods. Such methods and alternative or orthogonal options would greatly benefit bioanalytical labs in several aspects, including cost saving, method development and validation and GLP operation.
