Targeted HCP quantitation workflow utilizing versatile LC–MS methodologies

0

AVAILABLE ON DEMAND

During biotherapeutics manufacturing, process-related impurities and other trace contaminants accompany the recombinant biotherapeutic products. Among them, host cell proteins (HCPs) are a major type of protein impurity derived from the host organism. The detection and quantification of HCPs is an area of particular concern, as these contaminants can elicit an adverse response in patients. The high complexity and the wide dynamic range of protein concentrations in the multiple purification stages of biotherapeutic production poses challenges for the traditional data dependent workflows for HCP quantification. Therefore, targeted quantitation approaches with improved sensitivity have attracted more interest in industry. Herein, a comprehensive solution for targeted HCP quantitation utilizing various LC–MS platforms is presented.

What will you learn?

  • Background and relevance of host cell proteins in biotherapeutic process development.
  • Analytical challenges for effective identification and quantification of HCPs
  • How SCIEX’s LC–MS/MS solution can provide the most sensitivity and linear dynamic range for HCPs in highly complex samples

Who will this interest?

  • Scientists, researchers or lab directors working on host cell protein analysis or those considering doing so.
