TSKgel HIC-ADC Butyl

TSKgel® HIC-ADC Butyl – for antibody-drug-conjugate (ADC) analysis

The name gives it away: TSKgel HIC ADC columns are hydrophobic interaction chromatography columns designed for the analysis of Antibody-drug conjugates (ADCs). Tosoh has developed a new particle construction to achieve exceptional separation of variably conjugated ADC variants. This next-generation breakthrough in non-porous particle technology makes DAR analysis more reliable and improves separation efficiency. The TSKgel HIC-ADC-Butyl column sets a new industry standard with respect to the following characteristics:

    • Superior separation performance
    • Fast analyses (e.g. DAR determination in 7 minutes)
    • Reliability and lifetime

Due to their technical performance, these columns simplify method development and tech-transfer processes for DAR analyses. In addition, the TSKgel HIC-ADC-Butyl columns enhance both the accuracy and efficiency of Quality Control processes and enable the highest quality standards in ADC product.

Separation performance of the HIC-ADC column

The most important prerequisite to determining the Drug-Antibody-Ratio (DAR) in ADCs is maximum resolution between different payload variants. Individual peak areas can then be determined and used to calculate the average DAR. The column was benchmarked against other commercially available HIC columns. The TSKgel HIC-ADC Butyl column showed superior separation of DARs and their isoforms.
