Sartorius BIA Separations
QA (quaternary amine)
- Strong anion exchanger
- Working range, pH 2–13
- Binds molecules with predominantly negative charge, repels molecules a predominantly positive charge
- Use for capture, intermediate, or polishing steps in either bind-elute or flow-through mode
- High capacity for virus particles, IgM, exosomes
- High efficiency removal of endotoxin and DNA removal
Applications:
- Screening of chromatographic conditions (example binding, washing, elution conditions)
- High throughput of virus purification
