Characterizing the ratio of tumor-killing payload to cancer-binding antibody (DAR) is a critical quality attribute that helps determine the potential potency of a given antibody-drug conjugate (ADC) candidate. The TSKgel® HIC-ADC Butyl column, developed by Tosoh Bioscience, enables improved HIC-based separations for quantifying the DAR of ADCs.

Learn how to improve the accuracy of viral particle analysis using the combination of SEC-MALS and IEX.

This innovative AEX method replaces toxic TMAC with non-toxic choline-Cl, ensuring safety and efficiency in AAV capsid analysis, applicable across multiple AAV serotypes.

The increased demand for AAV therapies can be met by using LC-MALS to efficiently assess AAV purity without the financial burden.

MALS detection coupled with AEX chromatography can aid in the characterization of AAVs.

Adeno-associated viruses (AAVs) have recently gained significant attention in the field of gene and cell therapy. In this podcast, an overview of chromatography techniques for the characterization of AAVs will be discussed by Dr. Phu Duong. The discussion will highlight the most versatile and powerful detection technique to accurately characterize AAVs that is easy to adapt and implement.

Determine down to 8x10^9 AAV capsids and separate impurities of AAV samples by separation using a mixed-bed SEC column & highly sensitive MALS detection.

Polymers are gaining more attention in many new fields such as pharmaceutical applications. However, optimizing the final properties of the polymers associated with these new application areas is challenging for chemists and analysts. Polymer architecture plays a crucial role to optimize the end use or process-related properties. Size exclusion chromatography in combination with advanced detectors such as light scattering, viscometer, and refractive index is a powerful tool for the comprehensive characterization of macromolecules with various architectures. In this podcast, Dr. Subin Damodaran will explain how to understand the structural properties of a polymer by providing their molecular sizes such as radius of gyration (Rg ) and hydrodynamic radius (Rh), and intrinsic viscosity.
