Extractables and Leachables from Single Use Bioprocess Systems

Extractables and leachables (E&Ls) are small molecules present in a polymer system including antioxidants, surfactants, slip agents, plasticizers, acid scavengers, cross linking agents, residual monomers and oligomers, polymerization side...

Discover Single-Digit ppm Host Cell Proteins in Purified Antibody Samples

Recombinant biopharmaceutical proteins are expressed in host cell systems that contain numerous host cell proteins (HCPs). Even after a series of purifications, low levels of HCPs can remain in the purified biotherapeutics, which could reduce...

Peptide Mapping- A Comprehensive Workflow Solution from Sample to Answer

Peptide mapping is vital to understanding the structure of proteins and monitoring critical quality attributes. To create effective, high-quality biotherapeutics, you have to get this right. Renowned for accuracy and reliability, Agilent offers a...

2D-LC Solutions for the Analysis of Biopharmaceuticals

The presentation summarizes the latest updates for the analysis of biopharmaceuticals using the Agilent 1290 Infinity II 2D-LC Solution. After a short introduction to the principle mode of operation, I will explain the latest 2D-LC modes;...

Analysis of mAb N-glycans by HILIC

Routine analysis of therapeutic protein N-glycosylation has become important in biopharma discovery, development and QC labs. This presentation will briefly review recent advances in automated sample preparation and ultra-high performance HILIC...

Developing Workflow Solutions for Charge Variants and Aggregation Quantification

Biotherapeutics – recombinant proteins, such as monoclonal antibodies – are highly complex molecules produced by fermentation. Unlike small molecule drugs they can contain numerous sites of heterogeneity as well as other impurities (which can...
