Summary of "Triethylamine improves MS signals stability of diluted oligonucleotides caused by sample containers."

The effect of sample containers made of different materials on the MS-based analysis of oligonucleotides remains unknown. Here, we evaluated five types of sample containers on the MS signal stability of oligonucleotide, and they were normal glass insert, silanized glass insert with three different silanization techniques, and polypropylene sample vial. Also, we attempted to tackle signal stability issue by varying modifiers in dissolution solvent. Our results showed that sample containers made of different materials can significantly influence the MS signal stability of oligonucleotide at low concentration. Triethylamine (TEA) evidently improved both the signal stability and intensity of oligonucleotide.

Medical and Biotech [MESH] Definitions

Modified oligonucleotides in which one of the oxygens of the phosphate group is replaced with a sulfur atom.

The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.

A type of scanning probe microscopy in which a very sharp conducting needle is swept just a few angstroms above the surface of a sample. The tiny tunneling current that flows between the sample and the needle tip is measured, and from this are produced three-dimensional topographs. Due to the poor electron conductivity of most biological samples, thin metal coatings are deposited on the sample.

A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.

Sequences within RNA that regulate the processing, stability (RNA STABILITY) or translation (TRANSLATION, GENETIC) of RNA.
