Interaction of DNA with planar polystyrene surfaces coated with BSA. Wells of polystyrene microtiter plates were coated with BSA (100 ng/ml) as described in the Experimental section and, after washing, incubated overnight with DNA ranging in concentration from 0 to 5000 ng/ml. The amounts of BSA and DNA bound to the surface were assessed by ELISA using anti-BSA and anti-DNA (VAL-1205) antibodies, respectively. Error bars show the standard deviations from duplicate wells.
