Ampules of 2-Mercaptoethanol

These purified powders, convenient solutions, and solid-phase resins of disulfide reducing agents, including DTT, BME and TCEP, can be used to stabilize free sulfhydryls (cysteines) and to reduce disulfide bonds in peptides and proteins.

Product Function
2-Mercaptoethanol
Pure liquid (14 M), beta-mercaptoethanol (BME, 2BME, 2-ME, b-mer, CAS 60-24-2) is a thiol reducing agent for cleaving protein disulfide bonds (cystine).
2-Mercaptoethylamine-HCl
Pure crystalline 2-aminoethanethiol (2-MEA-HCl, also called cysteamine-HCl, CAS 156-57-0), selectively reduces antibody hinge-region disulfide bonds.
Bond-Breaker TCEP Solution, Neutral pH
Stable 0.5 M solution of TCEP reducing agent for protein disulfide bonds, odor-free and suitable as a 10X stock to make reducing SDS-PAGE sample buffers.
Cysteine-HCl Pure crystalline cysteine hydrochloride (Cys-HCl, CAS 52-89-1) is used to make the sulfhydryl assay standards or as an additive in protein refolding experiments.
Dithiothreitol
Pure crystalline dithiothreitol (DTT, CAS 3483-12-3) is a popular protein disulfide reducing agent for sample loading buffers.
TCEP-HCl
Pure crystalline Tris (2-carboxyethyl) phosphine hydrochloride, (TCEP, CAS 5961-85-3) is a thiol-free reductant for protein and peptide disulfide bonds.
TCEP-HCl, Premium Grade
Highly characterized version of a popular protein disulfide reducing agent thoroughly tested and fully documented.
Immobilized Reductant Columns
Thermo Scientific Pierce immobilized reductant column contains resin to which a thiol-based reducing agent has been immobilized to enable the solid-phase reduction of peptide and protein disulfide bonds.
Immobilized TCEP Disulfide Reducing Gel
Immobilized TCEP disulfide reducing gel is tris(2-carboxyethyl)phosphine covalently immobilized to agarose resin to help enable the efficient reduction of peptide and protein disulfide bonds without contaminating samples with reducing agent.
