It was then passed twice through SephadexG-25columnsto removethe Tris andca-codylate salts. Thelyophilized salt-free poly(dA-dT) wasre-dissolved in 0.1 Msodium phosphate, 1 mMEDTA, D20, pH6.3, tomakea30mM(P) solution. The poly(dA-dT) samples Jul 21, 2004 · CD and uv absorption data showed that high molecular weight poly(dA‐dT) · poly(dA‐dT), at 298 K, undergoes an acid‐induced transition from B‐double helix to random coil in NaCl solutions of different concentrations, ranging from 0.005 to 0.600M. Similarly, titration of the polynucleotide with a strong base causes duplex‐to‐single "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.

Poly(dA)·Poly(dT) molecules up to 1000 base pairs (bp) have been synthesized using enzymatic reaction, and characterization by STM observation shows that the DNA has no defects in the duplex structure. 01/11/2000 15/12/2014 poly(dA:dT) tracts or A-tracts, are overabundant in eukaryotic genomes. They have unusual structural, dynamic, and mechanical properties, and may resist sharp bending.

The reaction can be split under proper condition into two consecutive steps, the double helix formation of poly dA · poly dT and the addition of the poly U strand to form a trip · helix poly dA · poly dT · poly rU. The interaction energy of poly dA and dT has been determined to 34.3 kJ per mole base pairs and the interaction energy of a

Poly(dA:dT) is a repetitive dsDNA sequence of poly(dA-dT)∙poly(dA-dT) which functions asa synthetic analogue of B -form DNA. Minor groove narrowing is produced, in these two structures, not by overwinding of the helix, but by an increase in base pair propeller. This analysis confirms the concept that poly(dA-dT).poly(dA-dT) is polymorphous, with different local conformations possible in different local environments. Nov 01, 2000 · Poly (dA.dT) sequences (T-tracts) are abundant genomic DNA elements with unusual properties in vitro and an established role in transcriptional regulation of yeast genes. A plate reader was used to measure Stimulations with Alum (Pierce 77161) were performed by adding OD450 to calculate cytokine concentration. it to media to a final concentration of 500 lg/ml.

Compare Products: Select up to 4 products. *Please select more than one item to compare Poly (dA:dT) is a poly (deoxyadenylic-deoxythymidylic) acid sodium salt. 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 multiple PRRs: - Sensing by cytosolic DNA sensors ( CDS ), including cGAS, AIM2, DAI, DDX41, IFI16, and LRRFIP1, triggers the Poly(dA:dT), a ubiquitous promoter element that stimulates transcription via its intrinsic DNA structure. Many yeast promoters contain homopolymeric dA:dT sequences that affect nucleosome formation in vitro and are required for wild-type levels of transcription in vivo.

against 2 mM NaCl and 2 mM HEPES buffer (pH 7.8) at 2+4 C. Experiments were conducted at 1.2 C in low-temperature room thermostated at 4 0C. Such temperature was chosen because of two reasons. Poly(dA:dT) sequences are fragile because long single-strand poly(dA) stretches at the replication fork are unprotected by the replication protein A (RPA).
