Iodinated Compounds

OF

Radiometric detection is considered the gold standard for many applications, from drug discovery and development to plant sciences. 125I labeled compounds are useful in both basic research and drug discovery where they are used as tracers in radioimmunoassays (RIA) and ligands in binding studies. 125I is particularly versatile as it emits both gamma and Auger electrons. This means that can be it counted either directly, without requiring scintillation, or by using a liquid scintillation counter. We offer a wide range of 125I labeled compounds as well as customized services to label your unique compound.

We also provide customized services to 131I labeled your compound of interest.

For Research and investigative use only.

  • Alpha Bungarotoxin

    Triiodothyronine, ([125I]-T3), Specific Activity: 1080-1320 µCi/µg

    Triiodothyronine (T3) labeled with 125I. Triiodothyronine is a thyroid hormone that affects growth and development, body temperature, and heart rate. T3 detection by radioimmunoassay is a common test of thyroid gland function. This product is offered at three specific activities. Specific activity indicates how much radioactivity there is per molecule of ligand. Several of our 125I-labeled ligands are offered at maximum specific activity (2200 Ci/mmol if one 125I labeling site is available, 4400 Ci/mmol if two labeling sites are available).
    Price Range : 865.00 USD - 2500.00 USD
  • Alpha Bungarotoxin

    Insulin (human, recombinant), [125I]

    [125I]-Insulin (h) is suitable for the use in radioimmunoassay as well as receptor binding assay. [125I]-Insulin (h) is radioiodinated with no carrier added 125I using the LPO iodination procedure and is purified by reversed phase HPLC.
    Price Range : 1193.00 USD - 2324.00 USD
  • Alpha Bungarotoxin

    N-succinimidyl-3-(4-hydroxy-3-[125I]iodophenyl)propionate, Bolton-Hunter Reagent

    Bolton-Hunter reagent, monoiodinated. This product is used to iodinate proteins that do not contain tyrosine residues. Bolton-Hunter reagent is the N-hydroxysuccinimide ester of iodinated p-hydroxyphenylpropionic acid. The active ester acylates terminal amino groups with the iodinated p-hydxyphenylpropionic residue, effectively introducing radioactive iodine into proteins and peptides. A non-oxidative technique, it is less harsh to proteins than alternative labeling methods. An anhydrous benzene A charcoal trap is provided with each vial.
