Emerging Trends in Large Molecule Bioanalysis

  • Monday, October 19, 2015


The growth of biopharmaceuticals is increasing rapidly, driven largely by their enormous potential to treat a wide array of human diseases. Today, biotechnology products represent an estimated 24 percent of the world’s pharmaceutical sales and approximately 50 percent of the top 100 products on the market. Biopharma’s current annual growth rate of more than 8 percent is double that of conventional pharma, and growth is expected to continue at that rate for the foreseeable future. The growth does not come without challenges, and there is increased demand on the bioanalytical community supporting the development of biopharmaceuticals. To keep pace with the expanding field, bioanalytical scientists must continually revisit and reassess new technologies and operational approaches to the bioanalytical characterization of an ever-diversifying class of products.

The purpose of this webinar is to provide an educational forum to discuss current issues and applications associated with the analysis of large molecules in biological matrices. The webinar is designed to include and encourage open exchange of scientific and methodological applications for large molecule bioanalysis. Goals and objectives of this webinar include:

  • To provide a better understanding of the role and impact of critical reagents used in ligand binding assays.
  • To provide insight into the interpretation of FDA’s Bioanalytical Method Validation guidance document in a practical laboratory setting, with a special focus on matrix stability of protein therapeutics and on dilutional linearity and parallelism of therapeutics dosed at high concentration in toxicological studies.
  • To gain an understanding on the current state of the art of immunogenicity assessment.
  • To gain insight into analysis of biopharmaceuticals through innovations in mass spectrometry.
