Saturation kinetics for the binding of [3H]-9-cis-RA to pSG5/bcr1-PML/RARα (A) and pSG5/bcr3-PML/RARα (B) transiently transfected COS-1 cells. Specific t-RA binding activity (▪) is defined as total binding (•) minus nonspecific binding (○). Scatchard plot analysis of the saturation binding for bcr1-PML/RARα (C) and bcr3-PML/RARα (D).
