Autoradiogram of [125I]IAC44 (lanes 1 and 2), [125I]-N-IACoc (lanes 3 and 4), and [125I]IACoc (lanes 5 and 6) photolabeling of purified guinea pig sigma-1 receptor (26.1 kDa). Lanes 1, 3, and 5 show specificity of photolabeling with addition of 10 μM haloperidol. Lanes 2, 4, and 6 show photolabeling in the absence of 10 μM haloperidol.
