Abstract
Summary
Antibodies against conjugates of DDA and Malathion half ester with bovine fibrinogen were produced by sensitizing rabbits with these conjugates. No direct reaction was found against DDA or Malathion, but these compounds inhibited the hemagglutination of their respective conjugate. The antihapten antibodies were transitory, and their activity was lost during storage, unless frozen and kept at very low temperatures. Due to the hydrophobic nature of DDA, organic solvents were used in the precipitin and hemagglutination tests involving this compound.
