Validation of LC–MS/MS bioanalytical methods for protein therapeutics


“Of particular interest is LC–MS/MS analysis of therapeutic proteins via quantification of unique surrogate peptides that are produced by enzymatic digestion, a technique that is being widely used.”

There are more than 100 protein and peptide drugs currently approved by the US FDA and now over 100 more are currently in active development by pharmaceutical companies worldwide [1]. The quantification of protein therapeutics has traditionally relied upon ligand-binding assays (LBAs).
