Polyclonal and monoclonal antibodies (MoAbs) were raised against human
platelet thromboxane (Tx) synthase. Neither the antiserum nor the MoAbs
inhibited the enzyme activity significantly. Three MoAbs, Tu 300, Kon 6,
and Kon 7, were purified and further characterized. They are monospecific
as shown by activity precipitation or Western blot analysis, and recognized
different epitopes on Tx-synthase. Tu 300 could precipitate the enzyme and
recognized conformational epitopes, whereas Kon 6 and Kon 7 only reacted in
Western blots. Antibody Tu 300 can be used in immunohistology but shows no
crossreactivity with Tx- synthase from other species. In human lung tissue
staining with peroxidase, coupled Tu 300 was only found in alveolar
macrophages.
