Mixed-mode chromatography sorbents, HEA and PPA HyperCel™
Proteiinien puhdistukseen liuokset
HEA and PPA HyperCel™ sorbents are industry scalable chromatography sorbents designed for protein capture and impurity removal in a biopharmaceutical environment. Operating on a "mixed-mode" mechanism, their behavior is based on a combination of electrostatic and hydrophobic interactions of the proteins with the ligands. HEA and PPA HyperCel™ sorbents provide unique selectivities, different from those given by ion exchange or conventional HIC (hydrophobic interaction chromatography), that can be screened to facilitate process development.
