TRI Reagent ist ein einstufiges RNA-Isolierungsreagens, das die gleichzeitige Isolierung von DNA, RNA und Protein ermöglicht. In diesem Protokoll werden die Probenvorbereitung sowie die Extraktion verschiedener Proben und die Fehlerbehebung beschrieben.
The soaring global demand for energy, coupled with the limited supply of fossil fuels, has increased the need for renewable, low-cost energy sources. Organic electronics have shown great promise for applications in lighting, power, and circuitry, with rapidly improving performance
Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some
Supel Tox AflaZea SPE produced exceptional analyte recoveries with good reproducibility for all aflatoxins while requiring less than half the sample volume required by competing products.HPLC analysis of all spiked samples after SPE cleanup showed that all compared SPE cartridges

Samples for chromatographic purification should be clear and free from particulate matter. Simple steps to clarify a sample before beginning purification will avoid clogging the column, can reduce the need for stringent washing procedures, and can extend the life of
Stable isotope enrichment of recombinant proteins is necessary for most structure-function studies using NMR spectroscopy. The uniform incorporation of stable isotopes such as 13C, 15N and D into proteins is routinely accomplished by using bacterial expression systems such as Escherichia
A sensitive, quantitative, and reproducible SPME-GC/MS procedure was developed by Supelco for the extraction of phthalate esters from oily food matrices, such as the flavored oils included with ramen noodle kits.
