Description
5-Ethynyl-dUTP is a modified deoxyuridine triphosphate provided at min. 95 % purity as a 100 mM solution in water. The molecule is defined by CAS number 1004955-96-7 and empirical formula C₁₁H₁₅N₂O₁₄P₃, with a molar mass of 492,16 g/mol and a density of approximately 1 g/cm³. The 5-ethynyl substitution on the uracil ring introduces a terminal alkyne handle that can be addressed after incorporation into DNA. Stated purity, concentration and molar mass support precise dosing in polymerase reactions and subsequent conjugation steps. Available from manufacturer baseclick, this ethynyl-dUTP analogue serves chemical biology, molecular diagnostics and nucleic-acid probe development. The compact plastic format limits waste during method establishment while remaining practical for repeated small-volume withdrawals. Formula, density and CAS identifiers complete the technical profile required for laboratory records and controlled handling of specialised nucleotide reagents.

Questions about 5-Ethynyl-dUTP, min. 95 %, 100 mM in water, 10 µl, plastic
What is this article?
5-Ethynyl-dUTP, min. 95 %, 100 mM in water, 10 µl, plastic is the article on this page. Luminix Health distributes baseclick for laboratory use. It sits in Coenzymes, nucleotides & vitamins, inside Biochemicals & reagents, in Microbiology lab supplies.
Coenzymes, nucleotides and vitamins are the small molecules enzymes and cells consume: NAD, ATP, a vitamin cofactor. Purity, salt form and hydration are the specification, and many are unstable in solution or in the light. The lot is stored as the label says, often cold.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
