Disclosed are composite materials and methods of using them for chromatography. The composite materials retain their performance characteristics, such as binding capacity, flux, or percent recovery, under caustic conditions (e.g., 1 M NaOH for 24 h). In certain embodiments, the composite materials or membranes comprise a support member, comprising a plurality of pores extending through the support member; and a cross-linked gel. Importantly, the cross-linker and the monomer do not contain backbone ester linkages. The composite materials may be used in the separation or purification of a biological molecule or biological ion. |
