4-THIOURACIL Chemical Properties,Usage,Production

Description

4-Thiouracil is a site-specific, photoactivatable probe used to detect RNA structures and nucleic acid-nucleic acid contacts. It absorbs ultraviolet light >300 nm and, in the presence of oxygen, acts as an energy donor to produce singlet oxygen by triplet-triplet energy transfer. The highly reactive oxygen species then reacts readily with 4-thiouracil, leading to the production of uracil and uracil-6-sulfonate, which is fluorescent at a wavelength of ~390 nm. 4-Thiouracil is used as a T. gondii uracil phosphoribosyltransferase substrate to produce 4-thiouridine monophosphate, which can ultimately be incorporated into RNA.

Chemical Properties

yellow powder

Uses

4-Thiouracil is suitable reagent employed in Schneider′s media for the embryos during RNA extraction. It may be employed as reagent for the Northwestern blotting technique.

Uses

4-Thiouracil is a derivative of Uracil (U801000), which is a nitrogenous base in RNA nucleic acid. 4-Thiouracil is used for tagging in cell type-specific RNA isolation from intact complex tissues.
