Figure 1 Immunoprecipitation of secreted, precursor-labeled antigen with mouse mAb 3BD10 to TSHR-289.

Figure 1 Immunoprecipitation of secreted, precursor-labeled antigen with mouse mAb 3BD10 to TSHR-289.

CHO cells expressing TSHR-289 were precursor labeled with methionine/cysteine and immunoprecipitated with mouse mAb 3BD10. The mAb 3BD10 interacted strongly with native TSHR-289 (N) in culture medium, but not at all which is the same material after reduction and alkylation (D, denatured).

Figure 2 Monoclonal antibody recognition of TSHR N terminal synthetic peptides.

Figure 2 Monoclonal antibody recognition of TSHR N terminal synthetic peptides.

Upper panel, TSHR 20-mer peptides encompassed cysteine loops 1 and 2 (peptide A; residues 22–41), neither loop (peptide B; residues 37–56), and an overlapping peptide containing only loop 2 (peptide AB; residues 30–49). Cysteine residues known to form disulfide bonds in the TSHR are shown as black disks. Residue R38 in loop 2, the most N-terminal contact residue for human TSAb M22 is depicted as a gray disk. Lower panel, ELISA with the peptides indicated in panel A. Binding of the indicated mAb with each peptide (mean ± SEM of triplicate assays, each measured in duplicate). Antibody concentrations were 5 μg/ml 3BD10, 5 μg/ml 2C11, and 1:4 dilution of 3E5 containing culture medium.

Flow cytometry was performed using CHO cells stably expressing the TSHR ECD tethered to the plasma membrane by a GPI anchor. A, Deletion of TSHR loop 1 (amino acid residues 22–30; D22–30-ECD-GPI). Fluorescence values obtained using mAb 3BD10 were expressed relative to the control mAb normalized to 100%. Two experiments used both 2C11 and CS-17 as controls, and a third experiment used CS-17. All mAbs were at 10 μg/ml. Each bar represents the mean ± SEM of values obtained in three experiments. B, Chimeric substitution of loop 1 (TSHR amino acids 25–30 replaced with the corresponding LHR residues) A1-ECD-GPI. These experiments tested mAb 3BD10 (10 μg/ml) and also 3E5 (undiluted culture medium) relative to the control mAb 2C11 (10 μg/ml), fluorescence with the latter normalized to 100%. Each bar represents values (mean ± SEM) obtained in three experiments. C, The mAb 3BD10 binding kinetics. Flow cytometry was performed with increasing concentrations of mAb 3BD10 and mAb 2C11 as a control. Both antibodies are of the same IgG1 isotype. Each point represents the mean ± SEM of fluorescence values obtained in five experiments. Data were analyzed by nonlinear regression.
