Thorough Viscosity Characterization of Antibody Therapeutics




At the 2020 Peptalk Conference that took place in San Diego, our Principal Scientist, Dr. Stacey Elliott, gave a talk regarding a thorough investigation of antibody therapeutics using viscosity results.

1. How sensitive is viscosity change to concentration?

Extremely sensitive! We have done some sample concentration analysis with glycerol and small % changes can impact the viscosity significantly. Here are some sample application notes!

- L-Arginine Viscosity

- Concentration Protein Solutions

2. If you can do low concentrations, can you do high concentration measurements?

Yep! Similar to this application note, we have a number of more application notes that focus on various concentrations including higher concentration viscosity solutions. Check them out: 

- High Concentration Protein Solutions

- Optimization of Protein Solutions
