INSULIN (porcine), [125I], 10µCi (370kBq), Specific Activity:80-120µCi (2.96-4.44MBq)/µg

Insulin (porcine), labeled with 125I. Insulin is a peptide hormone that binds to insulin receptors to increase cellular uptake of glucose, increase DNA replication and protein synthesis, and modify enzymatic activity. This product is radioiodinated with 125I using a modification of the Hunter and Greenwood method and purified by ion-exchange column chromatography. This method predominantly labels tyrosine residues.

Detail Information

We offer radioligands and radiolabeled biomolecules to use as tracers, for radioimmunoassays (RIAs), for autoradiographic visualization, or for performing saturation and competition radioligand binding assays to determine receptor expression levels (Bmax), dissociation constants (Kd), association and dissociation rates (kon and koff), and inhibitor constants (Ki) 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 radiolabeled compounds is fully characterized for pharmacological action and validated in binding assays.

Radiochemicals remain the most sensitive method for probing 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.

Using the NENSure Packaging System from PerkinElmer

Since 1985, the unique NENSure system has set the standard for radiochemical packaging. Based on proven performance over millions of shipments, the system provides: Ease of use, Safe storage of unused product and Reduced radiation exposure. Many NEN brand research products, including 32P-, 33P-, 35S-, 3H-, 14C- and 125I-labeled compounds, are packaged in the NENSure System, as are most radionuclides.
