Description
1,4-Dithiothreitol is a high-purity reducing agent offered at minimum 99 % (p.a.) for protein biology and biochemical workflows. With CAS number 3483-12-3, empirical formula C₄H₁₀O₂S₂ and molar mass 154,2 g/mol, it is commonly known as DTT and is used to maintain thiol groups in the reduced state and to cleave disulfide bonds in proteins and peptides. Physical data include a density of 1 g/cm³, boiling point of 125 to 130 °C and flash point above 109 °C. The reagent (EG number 222-468-7) is Its strong reducing capacity and favourable solubility profile make it a standard laboratory chemical for controlling redox conditions during the handling of cysteine-containing biomolecules in research and analytical settings.

Questions about 1,4-Dithiothreitol, min. 99 %, p.a., 5 g, plastic
What is this article?
1,4-Dithiothreitol, min. 99 %, p.a., 5 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Protein biology (other), inside Protein biology & Western blot, in Microbiology lab supplies.
This shelf is the protein-biology article that is not a membrane and not an extraction kit: stains for gels, buffers, small tools of a protein bench. The method, a gel stain or a quantitation assay, still chooses the bottle.
Protein work separates a mixture, then asks which protein is which. Extraction and purification take the protein out of the cell. A marker shows the masses. A Western blot moves the separated proteins onto a membrane and probes them with an antibody. The membrane, nitrocellulose or PVDF, has to bind the protein and survive the washes. Antibodies and methods are in PubMed. Reference material is at ATCC.
Which category should I open next?
The category is Protein biology & Western blot. The sub-category is Protein biology (other). The catalogue is Microbiology lab supplies.
Shelves beside this one are Blotting membranes & papers and Protein extraction, purification & markers.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
