Polyethylene Glycols (aka. PEGs) are biologically inert, non-immunogenic, and hydrophilic molecules. These properties make them very attractive for research and drug discovery applications (ex. Antibody-Drug

Biomolecule conjugation is critical to many applications such as bead-based assays, ELISA and chromatography by affinity. Unfortunately the classical methods are known to be tedious and with low efficiency.

During the past decade, mass spectrometry, notably LC/MS, has become a major approach to identify and quantify proteins in patient samples. It includes analysis before treatments to find the proper biomarkers
