Beschreibung
In Vitro
Dansyl chloride is used to provide fluorescent labeling for protein studies. Dansyl chloride reacts with α-chymotrypsin, making it a method for studying α-amino and other reactive groups in proteins and peptides. Dan sulfonyl chloride is very useful for determining the amino acid sequences of small peptides. Dansyl chloride's a typical aromatic sulfonyl chloride that can react with a variety of bases to form derivatives of varying stability. Some recommended steps for peptides include: (1) reagents, buffers, and labeling mixtures (2) labeling the peptides (3) hydrolysis (4) visualization of compounds on paper (5) analyzing the results[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .
