A measurement buffer (50 ⁇ L) containing 2% dimethyl sulfoxide was added to examine the total binding, 50 ⁇ L of 4 ⁇ M non-labeled SP diluted with a measurement buffer containing 2% dimethyl sulfoxide was added to examine the nonspecific binding, and 50 ⁇ L of a test compound (containing 2% dimethyl sulfoxide) diluted with a measurement buffer was added to examine the binding inhibitory activity of the test compound.
  • a 125 I-Bolton Hunter substance P ( 125 I-BHSP) solution 50 ⁇ L was added to each well.
  • a cell harvester Perkin-Elmer
  • rapid filtration was carried out through GF/C filter plate (Perkin-Elmer) to stop the reaction and then GF/C filter plate was washed ten times with 250 ⁇ l of 50 mM Tris-HCl buffer (pH 7.4) containing 0.02% bovine serum albumin.
  • the GF/C filter plate was dried, microscinti-0 (20 ⁇ L) was added and the radioactivity was measured by TopCount (Perkin- Elmer) .
  • the GF/C filter plate had been immersed in
