Abstract

Specific high affinity BK binding sites in the nasal turbinate of the guinea pig have been demonstrated. Specific [³H]BK binding (10-330 pM) was saturable, and nonlinear least squares analysis indicated the presence of a high affinity binding site with a K_d value of 60 (50-78) pM and a B_max value of 13.1±2.0 fmol/mg protein. In inhibition experiments, D-Phe⁷-BK (a B₂ antagonist) inhibited [³H]BK binding with a K_i value of 23 nM, while des-Arg⁹[Leu⁸]-BK (a B₁ antagonist) had no effect up to a concentration of 10 μM. These studies indicate the presence of B₂ BK receptors in the guinea pig nasal turbinate.
