Prior to labeling, TCEP-HCl requires removal, presenting numerous advantages over DTT:
1 No Peculiar Smell: TCEP-HCl is odorless and can be used without the need for a fume hood.
2 High Stability: It maintains stability without concerns of oxidation during operation, use, and storage.
3 Wide pH Working Range: TCEP-HCl is effective across a broad pH range.
4 Strong Reducing Properties: In most experiments, 5-50mM TCEP-HCl offers significant molar force for complete disulfide bond reduction at room temperature within minutes.
5 Wide Compatibility: TCEP-HCl lacks thiol groups, eliminating the need for pre-removal in downstream thiol modification experiments like maleimide coupling.
Applications:
Gel Electrophoresis and Metal Ion Affinity Chromatography (IMAC): Used in preparation steps as a reducing agent to disrupt disulfide bonds within or between proteins.
Maleimide Coupling Reaction: Employed in coupling reactions with cysteine residues to prevent disulfide bond formation, unlike DTT or β-ME, ensuring efficient amine reactions with maleimide.
Homocysteine Measurement Kits: Utilized as a reducing agent to convert oxidized homocysteine into free homocysteine.
