L-CYSTEINE (15N) - Introduction
L-Cysteine-15N (L-cystein-15N) is a 15N isotope labeled cysteine. The following is an introduction to its nature, use, preparation and safety information:
Nature:
The molecular formula of the L-Cysteine-15N is C3H7NO2S, and the relative molecular mass is about 121.16. It is a colorless crystalline solid with a peculiar odor. It is soluble in water and ethanol, but not in ether.
Use:
L-Cysteine-15N are often used in isotope labeling experiments. By comparison with other isotopically labeled compounds, it is possible to trace the transformation pathway of the compound in the biochemical process. Especially in protein research, L-Cysteine-15N can be used to label cysteine residues in proteins to study the structure and function of proteins.
Preparation Method:
The preparation of the L-Cysteine-15N is usually carried out by a chemical synthesis method. First, the nitrogen isotope 15N of the amino atom is selectively introduced into the cysteine molecule, which can be labeled with a suitable 15N isotope labeling reagent. Then, through appropriate reaction and purification steps, the L-Cysteine-15N product with higher purity is obtained.
Safety Information:
The L-Cysteine-15N can be used safely under proper operation, but it is still necessary to pay attention to safe operation measures. It may have an irritating effect on the eyes, skin and respiratory tract, so contact should be avoided. When in use, wear appropriate personal protective equipment, such as laboratory gloves and protective glasses. In addition, it is recommended to operate in a well-ventilated laboratory environment. If ingested by mistake or breathing by mistake, seek medical assistance immediately.
