In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. 144-48-9, formula is C2H4INO, Name is 2-Iodoacetamide.Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles. COA of Formula: C2H4INO.
Mezger, Stephanie T. P.;Mingels, Alma M. A.;Bekers, Otto;Heeren, Ron M. A.;Cillero-Pastor, Berta research published 《 Mass Spectrometry Spatial-Omics on a Single Conductive Slide》, the research content is summarized as follows. Mass spectrometry imaging (MSI) can analyze the spatial distribution of hundreds of different mols. directly from tissue sections usually placed on conductive glass slides to provide conductivity on the sample surface. Addnl. experiments are often required for mol. identification using consecutive sections on membrane slides compatible with laser capture microdissection (LMD). In this work, we demonstrate for the first time the use of a single conductive slide for both matrix-assisted laser desorption ionization (MALDI)-MSI and direct proteomics. In this workflow, regions of interest can be directly ablated with LMD while preserving protein integrity. These results offer an alternative for MSI-based multimodal spatial-omics.
144-48-9, 2-Iodoacetamide is a synthetic retinoid that binds to the DNA of cells, altering transcription. It also has been found to be effective in treating bowel disease and has been shown to have dna binding activity. The compound was synthesized by attaching iodine molecules to acetamide. 2-Iodoacetamide targets the protein thiols on the surface of cells, which are responsible for oxidation and damage due to reactive oxygen species (ROS). This compound is metabolized by alcohol dehydrogenase and can be used as a biological sample or natural compound is a compound used as an electrophile for covalent modification of nucleophilic residues on proteins (cysteine, methionine, histidine). When modifying the active-site residues of cysteine proteases, α-Iodoacetamide acts as an irreversible inhibitor of these enzymes.
2-Iodoacetamide used in peptide mapping because it covalently binds with thiols in cysteine residues, thereby preventing disulfide bond formation. By virtue of reaction with cysteine, it is an irreversible inhibitor of enzymes with cysteine at the active site. Also reacts with histidine residues though much more slowly, and this activity is responsible for inhibition of ribonuclease.
