The objective of this application note is to demonstrate that the ACQUITY UPLC H-Class Bio System with 2D Technology is well suited for fractionation and enrichment of low abundant species in biological samples. A therapeutic monoclonal antibody, infliximab, was used to demonstrate this.
This comprehensive three-part series demonstrates that the ACQUITY H-Class Bio System with 2D Technology is well suited for the automated fractionation, desalting, and enrichment of biologically complex samples. The ACQUITY UPLC H-Class Bio System with 2D Technology offers an efficient solution with the flexibility needed for increasing informational content in the characterization of biotherapeutics without compromising productivity.
In this third part of the series, we address how to used 2D UPLC with downstream analyses such as peptide mapping, where peaks of interest may be present in low abundance, and how to apply an enrichment process to ensure digest efficiency and success with the subsequent assay.
