title: A monoclonal anti-thromboxane B2 antibody.
abstract: A monoclonal antibody against thromboxane B2 which may be used in standard fluid phase radioimmunoassays with a detection limit of around 40 pg and a binding affinity of 1.98 X 10(9) M-1 is described. Limited crossreactivity could be observed only with structurally closely related compounds such as 2,3-dinor-thromboxane B2 (8.9%), thromboxane B1 (15.7%) and thromboxane B3 (39.7%). Detectable crossreactivity with 11-dehydro-thromboxane B2, omega-carboxy-thromboxane B2, omega-hydroxy-thromboxane B2, prostaglandins of the D-, E- and F-type as well as metabolites of prostacyclin was lacking. The monoclonal anti-thromboxane B2 antibody proved well suited for measuring the thromboxane B2 content in tissue culture supernatants as well as in human serum.
