A top-down approach to quantifying intact proteins from biological fluids using liquid chromatography–triple quadrupole–mass spectrometry (LC–MS/MS) offers the potential for more absolute quantitation than bottom-up approaches. To make this broadly viable, however, commercial sample preparation tools are needed.

A method was developed for the molecular weight characterization of heterogeneous polymer mixtures, such as heparins and glatiramer acetate, noting that single molecular structures are not adequate for creating a molecular weight calibration curve. That limitation is overcome in this work, which demonstrates method validation and application to process samples.
