Aplicação

Ethylenediaminetetraacetic acid disodium salt dehydrate can be used to study molecular biology, biochemicals, solutions and reagents, biological buffers, DNA and RNA purification, inorganic salts, essential chemicals and chelators. Ethylenediaminetetraacetic acid disodium salt dehydrate has been used in a study to advance monitoring of illegal thyreostatic drugs in livestock. Ethylenediaminetetraacetic acid disodium salt dehydrate has also been used in a study for the determination of 232Th in seawater by ICP-MS after preconcentration and separation using a chelating resin.
Quelante de cátions divalentes. Inibe enzimas, como as metaloproteases, que requerem cátions divalentes para sua atividade.

Thyreostatic drugs, illegally administrated to livestock for fattening purposes, are banned in the European Union since 1981. For monitoring their illegal use, sensitive and specific analytical methods are required. In this context, the knowledge of the stability in a matrix

microRNA (miRNA) plays a role in the pathogenesis of ischemic stroke, and single nucleotide polymorphisms in miRNA genes may contribute to disease susceptibility. However, the effect of miR-146a, miR-196a2, and miR-499 polymorphisms on ischemic stroke susceptibility has been rarely reported.

End-functionalized macromolecular starch reagents, prepared by reductive amination, were grafted onto a urethane-linked polyester-based backbone using copper-catalyzed azide-alkyne cycloaddition (CuAAC) chemistry to produce novel amphiphilic hybrid graft copolymers. These copolymers represent the first examples of materials where the pendant chains

A novel method for selective determination of Cr(III) and Cr(VI) in environmental water samples was developed based on target-induced fluorescence quenching of glutathione-stabilized gold nanoclusters (GSH-Au NCs). Fluorescent GSH-Au NCs were synthesized by a one-step approach employing GSH as reducing/protecting
