Eliminate the need for antibodies and reduce assay time with direct detection using our radiolabeled ligands, which provide for sensitive and quantitative measurement of binding.
High specific activity — The majority of our 125I-labeled ligands are offered at maximum specific activity. This means virtually every molecule of ligand provided in the stock vial is radiolabeled. For tritiated ligands (3H ligands), pick a ligand with specific activity above 20 Ci/mmol – all of our tritiated ligands meets or exceeds these requirements.
High purity — We offer highly-pure radioligands for the highest specific signal with low background in binding assays.
High selectivity — Our broad portfolio of agonists and antagonists offers many options for choosing the most selective compound for your receptor.
Validated for receptor binding — all of our radioligand products are tested for receptor binding during development. Additionally, many of our radioligands are used to QC our GPCR and receptor cell lines and cell membrane products.
3H Muscimol radioligand. Muscimol acts as a potent selective agonist at GABAA receptors. It also acts as a partial agonist at GABAA-rho receptors. This product has a scheduled lot release for the second Monday in February and August. NOTE: NET574001MC will be obsolete soon.
Lysergic Acid Diethylamide (LSD), tritiated on the N-methyl group. LSD is a partial agonist of dopamine D2 receptors. It also binds most serotonin receptors (5-HT1A, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT5A, 5-HT5B and 5-HT6). This product has a scheduled lot release for the second Monday in April, August and December.
Levo-Norepinephrine, tritiated at the 7 position. Norepinephrine binds and activates adrenergic receptors, and is cleared by the norepinehprine transporter (NET). This product has a scheduled lot release for the third Monday in July.
Escitalopram (Cipralex), tritiated at the N-methyl position. Escitalopram is a selective serotonin reuptake inhibitor (SSRI) with high selectivity for the serotonin transporter (SERT) compared to the norepinephrine transporter (NET).
WAY-100635, tritiated on the methoxy group. WAY-100635 acts as an antagonist at serotonin 5-HT1A receptors. It also acts as an agonist at dopamine D4 receptors. WAY-100635 is on a scheduled release and is available on the second Monday in February and August.
N-Methyl-4-phenylpyridinium (MPP+) acetate, tritiated on the methyl group. MPP+ is a substrate for the organic cation ion transporter (OCT), the dopamine transporter (DAT), the norepinephrine transporter (NET), and the serotonin transporter (SERT).
2-D-Penicillamine, 5-D-Penicillamine (DPDPE), tritiated on the tyrosyl group. Cyclic peptide, sequence: Tyr-D-Pen-Gly-Phe-D-Pen-OH. DPDPE is a synthetic enkephalin opioid peptide that acts as an agonist at delta opiate receptors (δ-opioid receptor, DOR). This product has a scheduled lot release for the second Monday in February and August.
(+/-)-Epibatidine radioligand tritiated at the 5,6-biocycloheptyl position. Epibatidine has analgesic activities, has been shown to function as an agonist at nicotinic acetylcholine receptors, and has been shown to bind muscarinic and serotonin 5-HT3 receptors.
Paroxetine (Paxil), tritiated at the phenyl-6' position. Paroxetine is a selective serotonin reuptake inhibitor (SSRI). This product has a scheduled lot release for the first Monday in May and November.
5-hydroxytryptamine (5-HT, or serotonin) labeled with tritium. It is a naturally occurring neurotransmitter which is tied to positive mood, certain involuntary muscle control, and countless other functions.
DADLE, tritiated on the tyrosyl group. Peptide sequence: Tyr-D-Ala-Gly-L-Phe-D-Leu. DADLE is a synthetic enkephalin analog considered selective for the delta opioid receptor, but has been shown to bind the mu opioid receptor as well.
Acetylcholine (Ach) radioligand tritiated on the acetyl group. Acetylcholine is a neurotransmitter and the endogeous ligand that binds to and activates muscarinic and nicotinic acetylcholine receptors.
