일반 설명

Dithiothreitol (DTT) is used in proteomics applications to maintain sulfhydryl (-SH) groups in the reduced state and for quantitative reduction of disulfide (-S-S-) groups. It is a frequently used reagent in buffers due to its ability to reduce the oxidation state of a protein sample and preserves enzymatic activity. DTT is oxidized to the cyclic disulfide during the reduction of other disulfides in the solution.
Dithiothreitol is an effective reducing agent for protein analysis. The sealed-ampule format is convenient and easy to use when preparing samples for electrophoresis or other applications and avoids waste and loss of potency.

애플리케이션

DL-Dithiothreitol solution has been used:
  • in western blot analysis
  • as a supplement in lysis buffer to study its effects on sperm lysis
  • as a component of cold homogenization buffer, and chilled wash buffer for the isolation of nuclei from frozen rat tissues
  • in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), chromatography, modification of cysteine-containing compounds

mRNA decay is an essential and active process that allows cells to continuously adapt gene expression to internal and environmental cues. There are two mRNA degradation pathways: 3' to 5' and 5' to 3'. The DCPS protein is the scavenger

Sphingolipids are a family of eukaryotic lipids biosynthesized from sphingoid long-chain bases (LCBs). Sphingolipids are an essential class of lipids, as their depletion results in cell death. However, acute LCB supplementation is also toxic; thus, proper cellular LCB levels should

In this study, we investigated the role of inositol polyphosphate-4-phosphatase, type-II (INPP4B) in acute myeloid leukemia (AML). We observed that AML patients with high levels of INPP4B (INPP4B(high)) had poor response to induction therapy, shorter event-free survival and shorter overall

Pathogen effector proteins are delivered to host cells to suppress plant immunity. However, the mechanisms by which effector proteins function are largely unknown. Here we show that expression of XopP(Xoo), an effector of rice pathogen Xanthomonas oryzae pv. oryzae, in

Terminal uridylyl transferases (TUTs) function as integral regulators of microRNA (miRNA) biogenesis. Using biochemistry, single-molecule, and deep sequencing techniques, we here investigate the mechanism by which human TUT7 (also known as ZCCHC6) recognizes and uridylates precursor miRNAs (pre-miRNAs) in the
