Inhibitory binding constants (K_i, nM) for CRF ligands bound to CRFRs expressed in <i>E.coli</i> membranes as measured by competitive displacement of bound labeled astressin.

Ki values determined by analysis using competitive displacement of labeled astressin as described in Materials and Methods. r: rat; m: mouse; h: human. N.D.: No displacement. *Inhibitory binding constants (Ki, nM) for PD-sauvagine bound to CRFRs expressed in E. coli membranes were measured by competitive displacement of bound labeled PD-sauvagine.
