Figure 3. Analysis of selected chimeric rabbit/human anti-human ROR1 and ROR2 Fabs by flow cytometry.
(A) The binding of 13 purified chimeric rabbit/human anti-human ROR1 Fabs (10 μg/mL) to ectopically and stably expressed human ROR1 or human ROR2 on mouse pre-B cell line 63-12 and to parental 63-12 cells was analyzed by flow cytometry. Chimeric rabbit/human anti-human ROR2 Fab ERR2-TOP35 was used as control. (B) The binding of 12 purified chimeric rabbit/human anti-human ROR2 Fabs (10 μg/mL) to ectopically and stably expressed human ROR2 allotypes T245 and A245 and mouse ROR2 on HEK293F cells was analyzed by flow cytometry. Mock transfected HEK293F cells were used as control.
