Figure 1From: Oriented antibody immobilization to polystyrene macrocarriers for immunoassay modified with hydrazide derivatives of poly(meth)acrylic acidThe scheme of chemical modification of formylated polystyrene ball (FPSB) by acrylamide/methacryloyl hydrazide copolymers (CAMAH), which were obtained by processing copolymers of acrylamide and 4-nitrophenyl methacrylate (ANPAC) with hydrazine. A molar ratio m:n = 1:9 (CAMAH-1); 1:2 (CAMAH-2); 1:1 (CAMAH-3).Back to article page
