Conditions, such as solution pH, ionic strenght, solvent compoisition, termpature, light and electric field. These polymers are referred to as stimuli response, enivornmentally sensitive, "intelligent" or "smart" polymers. a large…

Co-precipitation of non-IgG contaminants with positvely chartged polymers parallels the selectivity of AEX. These reagents selectively co-precipitate acidic host cell protins, DNA and varous cell culture additivies. (Pete Gagnon, J.…

Anionic polyelectrolytes (polyanion polyelectrolytes)  include copolymers of acrylic acid, methacrylic acid and methyl methacrylate (US 8362217), polyacrylic acid (PAA), polystyrenesulfonic acid (PSS, poly(4-vinylbenzenesulfonate metal soat)), polymethacrylate (PMA), polyacrylamidomethylpropanesulfonate (PAMPS), carboxymethylcellulose (CMC),…

Introduction Hydroxyapatite is commonly used for purification of antibodies Gagnon (US2008/0177048).  Hydroxyapatite is chemically similar to the mineral component of bones and hard tissues in mammals. it is seldom pure…

Resins with multimodal ligands such as Capto MMC and Capto Adhere (GE Healthcare) can be used as polishing steps for antibody purificaiton. The multimodal functionality of the resin provides selectivity…
