The multiple reaction monitoring (MRM) method is a highly selective and sensitive approach for quantifying proteins and peptides in complex biological samples. Utilizing mass spectrometry, this technique targets and detects specific proteins while also identifying peptides and other protein fragments of interest. The growth of the MRM assay market is anticipated to be driven by increased research and development in the biological sciences during the analysis period, as there is a growing need to detect proteins and peptides in biological specimens.
