Analytical methods in biotechnology: introduction.

The objective of this meeting was to discuss a number of the new methods as they apply to the analysis of potential therapeutic proteins. The methods discussed ranged from electrophoretic and N- and C-terminal sequencing techniques, to the use of immunoassay methods for protein impurity detection and the application of mass spectrometry and NMR techniques to the characterisation of peptide protein and glycoprotein structure and oligosaccharide sequence. For each technique the authors have reviewed the current capabilities of the technique and then considered their future potential for use in characterisation of protein pharmaceuticals
