Carbimazole-dependent antibodies in enzyme immunoassay.Binding of carbimazole-dependent
antibodies in sera from 5 patients in the presence of the drug (1 mg/mL, solid bars) and without
drug (open bars).

Analysis of carbimazole-dependent antibodies by flow cytometry.Fixed platelets were incubated
with patient sera in the absence of the drug (A), in the presence of the drug (B), and in the
presence of the drug and soluble r-PECAM-1 (C).

Immunoprecipitation analysis of carbimazole-dependent antibodies.Platelets (A) and endothelial
cells (EC) (B) were surface-labeled with biotin and lysed.

Reactivity of carbimazole-dependent antibodies with platelets and endothelial cells.Carbimazoledependent antibodies were analyzed in MAIPA assay with endothelial cells (EC) or platelets
(Plts) either in the presence (solid bars) or in the absence (open bar...

Flow cytometric analysis of platelets with different PECAM-1 isoforms.Fixed platelets derived
from individuals carrying PECAM-1 Leu125 (A) or Val125 (B) isoforms were analyzed with patient
sera in the presence or in the absence of the drug (see Figure 3).

Immunoprecipitation analysis of carbimazole-dependent antibodies with PECAM-1
mutants.Untransfected L-cells and L-cells expressing the entire PECAM-1 or lacking the first
(Δ1) or the second (Δ2) extracellular immunoglobulin homology domain were surface labe...
