Figure S1. TCR and Fab 9B antibody binding to immobilized hCD1d-GSL monomers. (A) iNKT TCR binding response curve at equilibrium. Increasing concentrations from 1.5 to 48 ┬ÁM (twofold dilution) of iNKT TCR were injected for 30 s over the indicated hCD1d-GSL complexes. (B) Fab 9B antibody response curve at equilibrium. Increasing concentrations from 15 to 500 nM (twofold dilution) of Fab 9B antibody were injected for 90 s over the indicated hCD1d-GSL complexes.
