Dithiothreitol
Basic Information
Product name: dithiothreitol
CAS No.: 3483-12-3
Other name: DTT, DL-dithiothreitol
Molecular formula: C4H10O2S2
Molecular weight: 154.25
Appearance and character
White solid.
Application:
1. Commonly used reducing agent, which has anti-oxidation effect and participates in cell metabolism.
2. DTT has similar effects compared with mercaptoethanol, but the pungent odor of DTT is much smaller and the toxicity is much lower than that of mercaptoethanol. Moreover, when DTT is 7 times lower than the concentration of mercaptoethanol, the effects are similar.
3. Used as a protein sulfhydryl protecting agent. For the cleavage and sequence analysis of protein disulfide bonds. Sublimation at 37 ° C, 0.67 Pa. Micro moisture absorption. Soluble in water, ethanol, acetone, ethyl acetate, chloroform and ether. Slowly oxidize in the air.
