The results of CD47 binding assay showed a similar dose-dependent binding affinity of αCD47-G1 and αCD47-G4 to CD47(+) U251T2 GBM cells, demonstrating that the two antibodies have nearly equal binding affinity to the CD47(+) U251T2 cells (Fig. 1b). The gene discussed is CD47; the disease is glioblastoma.
