Porous nylon membranes modified with poly(acid) brushes and their derivatives can rapidly purify proteins via ion-exchange and metal-ion affinity interactions. Membranes containing poly(2-(methacryloyloxy)ethyl succinate) (poly(MES)) brushes bind 118 ± 8 mg of lysozyme per cm3 of membrane and facilitate purification of lysozyme from chicken egg white. Moreover, functionalization of the poly(MES) brushes with nitrilotriacetate (NTA)-Ni2+ complexes yields membranes that bind poly(histidine)-tagged (His-tagged) ubiquitin with a capacity of 85 ± 2 mg of protein per cm3 of membrane. Most importantly, the membranes modified with poly(MES)-NTA-Ni2+ allow isolation of His-tagged cellular retinaldehyde-binding protein directly from a cell extract in less than 10 min, and the protein purity is comparable to that achieved with commercial affinity columns. Thus, porous nylon membranes containing functionalized poly(MES) brushes are attractive candidates for rapid, high-capacity purification of His-tagged proteins from cell extracts.
