The hapten coated polystyrene support showed excellent stability as a function of the buffer pH and reaction time, and was successfully used to demonstrate its application in enzyme-linked immunosorbent assay (ELISA). %N 2 %K Hapten; Polystyrene; Silanization; ELISA %P 133-135 %V 506 %D 2004 %I Elsevier Science %R doi:10.1016/j.aca.2003.11.009 %L open951
