Product Description
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.
