Even with the advent of high throughput methods to detect modified ribonucleic acids (RNAs), mass spectrometry remains a reliable method to detect, characterize, and place post-transcriptional modifications within an RNA sequence. Here we have developed a stable isotope labeling comparative analysis of RNA digests (SIL-CARD) approach, which improves upon the original 18O/16O labeling …

Isotope Labeling There are many reasons to use custom-made isotope labeled organic molecules of all types. Isotopic labeling of compounds is a non-radioactive method of labeling, provides site-specific investigation of structures, makes molecules easily detectable by mass spectrometry and NMR, maintaining the physico-chemical properties of the target molecule, and is cost-effective and easy to

The state-of-the-art isotope-labeling schemes commonly employed for NMR investigations of high-molecular-weight proteins utilize selective incorporation of protons and 13C isotopes into methyl groups of Ileδ1, Leuδand Valγside chains in a highly deuterated environment (commonly referred to as “ILV labeling”) providing a large number of high-quality probes for NMR studies of protein structure and dynamics.

5). Isotope labeling and IR spectroscopy have been used previously to study amyloids, which have provided insight into general aggregation mechanisms (11, 12).

Isotope labeling is a technique used to track isotopes (atoms with detectable neutron count changes) through reactions, metabolic pathways, or cellular channels. The reactant is "labeled" by replacing specific atoms with its isotopes. The reactant is then allowed to undergo the reaction.

SIL (Stable Isotope-Labeled) protein standard for protein quantification using line for control antigens (PrEST Antigen™) and heavy isotope labeled protein Buy Benzonatate-d9, a potentially useful isotope labeled Benzonatate, from Santa Cruz.

Stable isotope labeling with amino acids in cell culture (SILAC) is a powerful method to identify and quantify relative differential changes in complex protein samples. This approach entails the in vivo metabolic incorporation of 'heavy' 13 C- or 15 N-labeled amino acids into proteins followed by mass spectrometry (MS) for the accelerated and comprehensive identification, characterization and Metabolic labeling, also referred to as biosynthetic labeling, relies on simple organisms, which are able to incorporate stable isotope labeled nutrients into their biomolecules. The first studies were conducted in bacteria such as Escherichia coli , where growth media with a single carbon or nitrogen source were used.

As one of the world’s leading radio-labeling groups we have a reputation for excellence in synthetic chemistry enabling us to carry out the most challenging synthetic projects. Sources of isotopes used for labeling The simplest labeling, and also the cheapest one is 15 N, because 15 N ammonia is quite cheap. 13 C is more expensive, because it requires the synthesis (most commonly - biosynthesis) of 13 C glucose, some expression systems allow use of cheaper 13 CO 2 . The labeling takes place by exchanging a specific atom with their isotope. The detecting of the isotopes in the product helps to understand the possible mechanism and the stereochemistry in this sequence of the reaction.
