Lysergic Acid Diethylamide (LSD) is a psychedelic drug that acts as an agonist at dopamine D₂ receptors and serotonin receptors 5-HT_1A, 5-HT_2A, 5-HT_2B, 5-HT_2C, 5-HT_5A, 5-HT_5B and 5-HT₆.

We offer both agonist and antagonist radioligands for autoradiographic visualization or performing saturation and competition assays to determine receptor expression levels (B_max), dissociation constants (K_d), association and dissociation rates (k_on and k_off), and inhibitor constants (K_i) for a variety of receptors. We develop our radioligands to the highest specific activity possible and provide high purity resulting in low non-specific binding products. Each of our ultra-pure radioligands is fully characterized for pharmacological action and validated in receptor binding assays.

Radiolabeled ligands remain the most sensitive method for probing receptor binding biology; yielding unprecedented sensitivity gives results that technicians and scientists can trust. For over 50 years, PerkinElmer has been a leading supplier of New Englａnd Nuclear (NEN) radiochemicals, liquid scintillation cocktails, vials and nuclear counting detection instruments.
