The synthetic DNA exhibits a dinucleotide repeat conformation on addition of CsF and Me4NCl at molar concentrations, with the NMR spectral changes reflecting a common conformational change at one glycosidic "Poly dA-dT" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. It is a repetitive synthetic double-stranded DNA sequence of poly(dA-dT); poly(dT-dA) and a synthetic analog of B-DNA. Poly(dA:dT) is recognized by several sensors, including DAI, LRRFIP1 and AIM2. Poly(dA:dT) is also indirectly detected by RIG-I. The activity of poly(dA:dT) is tested using the reporter cell line B16-Blue™ IFNα/β. Circular dichroism was used to study changes in conformation of poly(dA-dC).poly(dG-dT) caused by a high concentration of various monovalent salts. It was found that CsF induced the gradual appearance of a negative band in the long wavelength part of the CD spectrum of poly(dA-dC).poly(dG-dT), which might reflect a transition of this DNA toward (1983).

The Sigma catalogue has four ranges: the 1-series, the all-mahogany 15-series, plus the Standard and Vintage series. The DR-41, from the Standard series, is adorned with generous ornamentation as featured within the soundhole rosette, the top's edging and hexagon-shaped fretboard markers.

The results suggest … Using a protein ligation method, we develop a general approach for linking the immune stimulant, poly dA:dT (pdA:dT), to a monoclonal antibody (mAb) specific for DEC205 (DEC). We show that DEC-specific mAbs deliver pdA:dT to DCs for the efficient production of type I interferon in human monocyte-derived DCs and in mice. Notably, adaptive T-cell immunity is elicited when mAbs … 08/12/2009 Sigma factor, an essential component of the transcription machinery in E.coli, is released at the poly (dA-dT) tract once the transcription is initiated (13).
