What is the right number of replicates in biopharmaceutical analysis? Does the answer depend on the type of analysis?

In response to regulatory concerns, host cell protein (HCP) analysis is now often conducted using LC–MS/MS. Unlike ELISA, LC–MS/MS can positively identify and quantify specific HCPs and characterize the total amount of HCPs present.

Recent assessments of four biosimilars illustrate how a combination of orthogonal, high-resolution tools is used to demonstrate analytical and functional biosimilarity.

Charge detection mass spectrometry (CDMS) is a useful tool to characterize larger, more complex biopharmaceuticals like bispecific antibodies and ADCs.

We review different approaches and coupling strategies for analyzing monoclonal antibody aggregates with 2D-LC.

Intact mass analysis is becoming increasingly useful for characterizing biologics. We describe the current application of intact mass analysis, including quantitation, sequencing, and structural characterization.
