Description
1,4-Dithioerythritol is a high-purity thiol reagent supplied at min. 99 %, p.a., with CAS number 6892-68-8 and empirical formula C₄H₁₀O₂S₂. Its molar mass is 154,2 g/mol, supporting precise dosing in analytical and molecular biology workflows. This reducing agent is widely used to cleave disulfide bonds, protect free thiols, and maintain proteins or enzymes in a reduced state during sample preparation, electrophoresis, and related life-science protocols. The p.a. grade supports routine laboratory synthesis and biochemical applications that require a defined dithiol reductant. Laboratories can integrate this compact glass pack into stock systems for protein chemistry, nucleic-acid work-up, and other disulfide-sensitive procedures without unnecessary bulk. Clear CAS, EG, and formula identifiers facilitate documentation, ordering, and method transfer across research and quality-control environments.

Questions about 1,4-Dithioerythritol, min. 99 %, p.a., 5 g, glass
What is this article?
1,4-Dithioerythritol, min. 99 %, p.a., 5 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Molecular biology reagents (other), inside Molecular biology, in Microbiology lab supplies.
These are the molecular-biology reagents that are not an extraction kit and not a PCR master mix: buffers, dyes, ladders' companions, modifying enzymes. Nuclease-free is a claimed property and the reason the bottle costs what it does. A laboratory-grade chemical of the same formula is not a substitute.
Molecular biology here is the handling of DNA and RNA. Extraction kits break the cell and then separate the nucleic acid from protein and from the other nucleic acid. PCR and qPCR reagents copy a chosen sequence so it can be seen. The enzymes and the nucleotides are what the copy depends on. Nuclease contamination destroys the sample before the kit can save it. Sequences are on NCBI Nucleotide. Papers are on PubMed.
Which category should I open next?
The category is Molecular biology. The sub-category is Molecular biology reagents (other). The catalogue is Microbiology lab supplies.
