Structural determination by NMR is an important tool for understanding protein form and function. 13C, 15N, D labeled carbohydrates and amino acids as part of the expression system allows for targeted protein site studies. Or, if efficiency gains are needed, consider the benefits of ISOGRO® isotopically-labeled media.



The use of stable isotope labeled metabolites to render visible metabolic images of the body offers insight into metabolism of both disease and healthy tissues. ISOTEC® is committed to
offering an extensive array of labeled compounds for this purpose, many available from our GMP facility.



Enhanced molecular biology research by using selectively-labeled RNA phosphoramidites to synthesize labeled oligonucleotides. Labeled probes allow for site-specific interrogation.


Methyl labeling kits

Methyl groups are ideal probes for studying protein structure and function by NMR. Comprehensive easy to use kits lead to isotopic labeling of a variety of amino acid residues.
