Summary
The effects of different membrane preparations and assay conditions on [3H]5-HT binding to post-mortem human cortical tissue was studied. Optimal binding necessitated thorough removal of endogenous 5-HT and this was achieved either by hypotonic lysis or by preincubation of the membranes at 37‡C. Calcium chloride (4 mM) increased specific [3H]5-HT binding. The further addition of ascorbic acid (5.7 mM) or ascorbic acid and clorgyline (10 ΜM) reduced specific [3H]5-HT binding.
