Cuboid Size-Exclusion Chromatography Device for Biopharmaceutical Purification – 21-043, 16-062

Abstract

Size exclusion chromatography (SEC) has been widely used for the analysis of biopharmaceuticals. However, limitations such as low speed, low capacity, and poor scalability of commercial SEC columns make them unsuitable for preparative purification of biopharmaceuticals. To address these issues, researchers at McMaster University have developed a scalable cuboid SEC device which has a short bed height, large cross-sectional area, and a unique flow distribution & collection system. Compared to conventional SEC columns, this novel SEC device has higher speed and productivity, lower operating pressure, higher resolution, and higher loading capacity.

Applications

• Purification of biopharmaceuticals such as antibodies, vaccines, and other life-saving therapeutics
• Purification of viruses and virus like particles (VLP)
• Purification exosomes and other vesicles
• Purification of liposomes and nanoparticles

Advantages

• Low operating pressure
• High loading capacity of sample
• High resolution of purification
• Fast separation
• Scalable device
