Description
TEMED (N,N,N′,N′-tetramethylethylenediamine) is a high-purity reagent, minimum 99 %, p.a., intended for electrophoresis applications. It has the empirical formula C₆H₁₆N₂, CAS number 110-18-9 and EG nr. 203-744-6, with a molar mass of 116,21 g/mol. Physical data include a density of 0,776 g/cm³, a boiling point of 118,7 °C and a flash point of 21 °C. In polyacrylamide gel electrophoresis, TEMED catalyses free-radical polymerisation of acrylamide and bis-acrylamide in the presence of persulfate initiators, enabling controlled gel formation for protein and nucleic-acid separations. This grade from manufacturer Carl ROTH is The p.a. specification supports analytical and research use where reagent quality influences gel reproducibility. Store and handle as a flammable liquid in accordance with laboratory safety procedures. size is practical for routine casting of analytical and preparative gels.

Questions about TEMED, min. 99 %, p.a, for electrophoresis, 100 ml, glass
What is this article?
TEMED, min. 99 %, p.a, for electrophoresis, 100 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Gels, combs & casting accessories, inside Electrophoresis, in Microbiology lab supplies.
A gel, a comb and a casting tray make the slab a sample runs through. Agarose percentage, or the acrylamide mix, sets the sieve. The comb thickness and the number of teeth set the wells. Precast and hand-cast gels are different products. A comb for a different tray does not seal.
Electrophoresis pulls charged molecules through a gel. Smaller ones move farther. Agarose gels separate nucleic acids. Polyacrylamide gels separate proteins. A comb forms the wells. A power supply holds the voltage or the current. The gel percentage is the sieve. A marker lane is how the bands are named. The methods are in the PubMed literature. Sequences of the nucleic acids are on NCBI Nucleotide.
