Anwendung

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.

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
