Highly Cross Linked Strong Anion Exchanger
Our always-ready technical support and service teams go the extra step to be your most trusted resource. We're here for you.
Praesto® Q90 is an agarose-based strong anion exchange resin, designed for large scale biomolecule purification, including proteins, peptides and oligonucleotides. The relatively large particle size (90 µm) makes Praesto® Q90 ideal for capture or intermediate purification of proteins when large sample volumes needs to be processed within a limited time frame.
