Histidine Containing Macroporous Affinity Cryogels for Immunoglobulin G Purification
A supermacroporous cryogel was prepared to obtain an efficient and cost effective purification of IgG from human plasma. N-methacryloyl-(L)-histidine methyl ester (MAH) was chosen as the pseudospecific ligand and/or comonomer. Poly(hydroxyethyl methacrylate-N-methacryloyl-(L)-histidine methylester) [PHEMAH] cryogel was produced by free radical polymerization initiated by N,N,N′,N′-tetramethylene d
