Binding of human anti-NR1 mAbs to plate-adherent ATD. ATD mobilized by TEV protease treatment of 293T-ATD cells was captured by a Myc tag antibody and tested for binding by commercial and human mAbs. a Murine anti-NR1 mAb. b Human mAbs, 5F5, 2G6, 1D1, and 6A (isotype control). All samples were tested in triplicate. RLV, relative luminescence value; Ctrl, buffer only. Bars indicate the S.E.M.
