Light Scattering for Biopolymer Characterization
Objective: To provide an introduction on how static and dynamic light scattering detectors determine absolute molar mass, size, and conformation of biopolymers in solution. Various applications and new tools including protein conjugate analysis, field flow fractionation, and automated DLS will be discussed.
Speaker: Dr. Michelle Chen, Head of Analytical Services at Wyatt Technology, graduated from the Chemical Engineering Department, Yale University, under the advisory of late Professor Csaba Horvath. At WTC, she has been working with polymer characterization using different light scattering techniques in conjunction with various branches of HPLC and FFF.
Agenda:
Introduction to light-scattering theory 15 min
How absolute molar mass and size are determined
Flowing mode – on-line MALS and QELS
MALS-UV-RI: measuring extinction coefficient and protein conjugates
Batch mode - use of flow cell, scintillation vials and microCuvette
Polymer characterization using MALS/QELS detection 10 min
Measure absolute MW and hydrodynamic radius
Determine oligomerization states of proteins and aggregation
Provide preliminary structural analysis
Characterize protein conjugates, membrane proteins
Obtain size/distribution information of micelles and liposomes
Example applications 20 min
Questions and comments 15 min
