Sartorius BIA Separations
PrimaS
- Multimodal chromatography ligand that combines elements of hydrogen bonding with anion exchange chromatography
- Offers unique selectivities in many important product areas
- Supports purification of single-stranded RNA at ambient temperature and also fractionates ssRNA by size
- Bacteriophage purification: Provides superior reduction of endotoxins (up to 7 log removal) compared to strong anion-exchangers (e.g., QA).
For sensitive separations where reproducible chromatography is essential (e.g., AAV empty – full separation), we have developed PrimaS HR column with strict release criteria, ensuring reproducible column performance.
IMPORTANT NOTICE: Column lifetime affected by > 0.1 M NaOH. See updated column stability and cleaning instructions on the Product sheet.
