Blocking of anticoagulant effect of heparin by antiheparin antibodies.
Periplasmic fractions containing antiheparin antibodies were allowed to bind to Protein A Sepharose. The beads were washed and the antibody-bead complexes were used in an APTT assay. Note the complete inhibition of the anticoagulant effect of heparin by EW4B5. Values are mean ± SD (n = 3).
