Neuroblastoma× glioma hybrid cells (NG108-15) were used as a model system to characterize neuronal-glial type angiotensin (ANG) receptors by covalent crosslinking analysis. After differentiation with 1.5% DMSO and 0.5% fetal bovine serum for four to five days, saturation analysis revealed a single high affinity site with a K d= 1.35±0.42 nM and a B max= 468±106 fmol/mg protein. Using the homobifunctional crosslinking reagent bis (sulfosuccinimidyl) suberate (BS 3), a site with an estimated M r of 78 kDa was specifically labeled with 125 I-ANG II as determined by SDS-polyacrylamide gel electrophoresis. Both ANG II and ANG III (10− 6 M) inhibited specific labeling. The K i for ANG III binding was similar by both pharmacologic (K i= 3.33±0.98 nM) and gel densitometric (K i= 2.65±0.32 nM) analyses. We conclude that the 78 kDa protein represents a high affinity ANG binding site with similar affinities for both ANG II and ANG III.
