One-third of eukaryotic proteins are integrated within membranes, as are the targets of 40% of approved drugs. However, the lack of a general means of solubilizing, stabilizing and structurally characterizing active membrane proteins has frustrated efforts to understand their mechanisms

A new male method of contraception by injecting a polymer, styrene-maleic anhydride (SMA), into the lumen of the vas deferens has been studied on rhesus monkeys. The polymer has the dual feature that it can occlude the vas deferens lumen

We developed an improved method to chemically immobilize antibodies on a nylon surface using a styrene maleic anhydride copolymer having an aryl group, which provides hydrophobicity to the nylon surface. We applied it to a modified enzyme-linked immunosorbent assay (slip-ELISA)
