DL-1,4-Dithiothreitol (CAS 3483-12-3) Overview

DL-1,4-Dithiothreitol (DTT), CAS 3483-12-3, is a potent reducing agent widely used to break disulfide bonds in proteins and stabilize enzymes. With molecular formula C₄H₁₀O₂S₂ and molar mass 154.25 g/mol, it operates effectively in pH ranges 6.0-9.0.

Key Parameters & Comparative Analysis

Applications in Biochemical Research

1. Protein Denaturation: Breaks S-S bonds in SDS-PAGE sample prep.
2. Enzyme Stabilization: Maintains activity of sulfhydryl-dependent enzymes.
3. Nucleic Acid Studies: Prevents RNA/DNA degradation by nucleases.

Step-by-Step Usage Protocols

Western Blotting Protocol:
1. Prepare 1M DTT stock in 0.01M sodium acetate (pH 5.2)
2. Add 50-100mM final concentration to sample buffer
3. Heat samples at 95°C for 5 minutes before electrophoresis
