Agilent Bio-Monolith Protein A Monitors Monoclonal Antibody Titer from Cell Cultures
March 25, 2014

To monitor monoclonal antibody titer and yield from cell-culture supernatants before expensive prep and large amounts of Protein A are employed, an analytical scale procedure helps determine the titer of monoclonal antibody for the optimal time for harvest of the mAb product. Here, pre-packed Agilent Bio-Monolith Protein A columns quickly capture mAb titer from cell supernatant.

Peptide Mapping of Glycoprotein Erythropoietin by HILIC LC/MS and RP-LC/MS
March 25, 2014

In this application note an Agilent ZORBAX Rapid Resolution High Definition (RRHD) 300-HILIC 1.8 ?m column and an Agilent AdvanceBio Peptide Mapping column are used in combination with time of flight (TOF) mass-spectrometry (MS) for mapping EPO protein. The work demonstrates the utility of HILIC as an orthogonal and complementary approach to reversed-phase LC/MS for peptide analysis.
