Analytics and Characterisation Library
Protein characterisation is an essential part of recombinant protein production, enabling quality control check on a purified or partially purified protein.
Modern, sensitive techniques enable physical properties such as mass, size, concentration, amino acid sequence, stability and structure of a protein to be determined. Other methodologies, often protein-specific, can be used to elucidate biological functioning.
Some of the more commonly encountered characterisation techniques are described below.
Structural Characterization of a Recombinant Fusion Protein by Instrumental Analysis and Molecular Modeling.
Wu Z, et al. PLoS ONE. 8(3), e57642 (2013)
Characterization of Globular Protein Solutions by Dynamic Light Scattering, Electrophoretic Mobility, and Viscosity Measurements.
