Register：Best Practices in Host Cell Impurity Analytics – Using Advanced Technologies and Methods to Monitor, Control and Quantify Host Cell Proteins - 1730233

Event Overview:

Host cell protein (HCP) analytics have come a long way over the last 25 years. We have gone from a “black box” type approach that produced semiquantitative numbers at best to groundbreaking mass spectrometry (MS) techniques that can identify every host cell protein in a Drug Substance sample. While the HCP ELISA is still semi-quantitative today, it is by no means a black box. We now have the tools to know exactly which HCP the assay can detect and which ones it will miss. We will discuss how the adoption of advanced technologies and methods for HCP analytics ensures that an HCP ELISA, whether it is a generic or a process-specific assay, is appropriate for use and allows data driven risk assessment to ensure the integrity and safety of a drug product. We will also present several case studies focusing on HCP antibody coverage assessment utilizing 2D PAGE- and MS-based methods. Additionally, data on Cygnus CHO Lipase Assay using stable isotope labeled peptides and PRM-MS absolute quantification method will be presented.

Key Learning Objectives:

 Walkthrough a brief history and advances made in HCP analytics

 Understand HCP ELISA selection and how to ensure the selected assay is appropriate

 Learn advanced methods for HCP antibody coverage analysis, HCP identification, and quantification in drug substance samples
