Radiometric detection is considered the gold standard for many applications, from drug discovery and development to plant sciences. The technique achieves sub-femtogram sensitivity levels, and quantitates the binding and activity of radiolabeled compounds with high specificity and sensitivity. As the leading supplier of research radiochemicals, we offer a broad portfolio of products for any radiochemistry need.
Our radiochemical analysis products include:
Radionuclides such as 14C, 89Zr, 125I, 32P, 35S, 3H, 45Ca, 51Cr, 55Fe
EasyTag™ protein labeling mixes
EasyTide radiolabeled nucleotides
NEN radiolabeled compounds
SPA Enzymatic assays and imaging beads
Our radiolabeled compounds are useful in a wide range of applications:
Research in cancer, CNS and neurologic disease, cardiovascular and metabolic disease, inflammation, and other disorders
Kinetic and mechanistic studies
Radiometric cAMP assays
Detection of binding to over 80 different receptor types
Our radiometric reagents are not reliant on the use of antibodies for detection and read-out – just one of the reasons they are so widely used.
Levo-Norepinephrine, tritiated at the 7 position. Norepinephrine binds and activates adrenergic receptors, and is cleared by the norepinehprine transporter (NET). This product has scheduled lot release dates for the third Monday in January and July.
Deoxycytidine triphosphate (dCTP) is a nucleoside triphosphate that is used whenever DNA is synthesized, such as in the polymerase chain reaction. 125I dCTP may be used to produce cDNA transcripts of viral or mRNA.
cAMP, labeled with 125I on the tyrosine methyl ester group. I-125 labeled cAMP can be used as a tracer for radioimmunoassays to detect levels of endogenous cAMP in a sample or for GPCR functional assays.
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.
Epibatidine, labeled with 125I. 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.
