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.
8-OH-DPAT radioligand tritiated at the 1,2,3 position on the propyl-2,3-ring. 8-OH-DPAT is a serotonin receptor agonist specific for the 5-HT1A and 5-HT7 receptors.
5-Hydroxytryptamine Binoxalate (Serotonin Binoxalate), labeled with C-14 at the 1-position. 5-Hydroxytryptamine is a neurotransmitter and is the endogenous ligand for serotonin receptors. NEC855 replaces product NEC225, which was labeled at the 2-position.
5-carboxyamidotryptamine (5-CT) labeled with tritium. 5-CT is a tryptamine derivative closely related to the neurotransmitter serotonin. 5-CT acts as a non-selective, high-affinity full agonist at the 5-HT1A, 5-HT1B, 5-HT1D, 5-HT5A, and 5-HT7 serotonin receptors. It also binds the 5-HT2, 5-HT3, 5-HT6 serotonin receptors with lower affinity.
5-Hydroxytryptamine Creatinine Sulfate (Serotonin, 5-HT), tritiated at the 1,2 position. 5-Hydroxytryptamine is a neurotransmitter and is the endogenous ligand for serotonin receptors.
CP 55,940, tritiated on the side chain-2,3-4 position. CP 55,940 is a synthetic cannabinoid that acts as a full agonist at both cannabinoid CB1 and CB2 receptors, and can also upregulate serotonin 5-HT2A receptors.
Tritiated gabapentin (Neurontin). Gabapentin is a medication used to treat epilepsy, and has been shown to cross membrane lipid barriers via system L-amino acid transporters and bind to voltage-gated calcium channels in the central nervous system. This product has a scheduled release for the third Monday in February and September.
Cocaine, tritiated at the benzoyl-3,4 position. Cocaine binds and blocks the dopamine transporter, preventing removal of dopamine from synapses in the brain.
AFDX-384 (BIBN-161) radioligand tritiated at the 2,3-dipropylamino position. AFDX-384 acts as a selective antagonist of muscarinic acetylcholine receptors, with selectivity for the M2 and M4 subtypes.
5'-N-Ethylcarboxamidoadenosine (NECA), tritiated at the adenine-2,8 position. 5'-N-Ethylcarboxamidoadenosine is an adenosine analog that acts as an agonist at adenosine receptors A1, A2A, and A3.
