DNA ligands that bind tightly and selectively to cellobiose.
Cell surface oligosaccharides have been shown to play essential biological roles in such diverse biological phenomena as cellular adhesion, molecular recognition, and inflammatory response. The development of high-affinity ligands capable of selectively recognizing a variety of small motifs in different oligosaccharides would be of significant interest as experimental and diagnostic tools. As a...
متن کاملIncreased thermal stability of chromatin containing 5-bromodeoxyuridine-substituted DNA.
The replacement of thymidine by 5-bromodeoxyuridine in DNA leads to a greatly enhanced stability of chromatin from hepatoma tissue culture or embryonic rat pancreas, as measured by thermal chromatography on hydroxylapatite. The increased stability is directly correlated with the degree of bromodeoxyuridine substitution. On the other hand, the incorporation of bromodeoxyuridine into DNA results ...
متن کاملThermal denaturation of DNA from bromodeoxyuridine substituted cells
The thermal denaturation of DNA from cell lines extensively substituted with bromodeoxyuridine has been examined spectrophotometrically over a wide range in ionic strength and by thermal elution from hydroxyapatite columns. BrdU substitution stabliizes DNA at all ionic strengths between 7.5 mM and 1350 mM potassium ion concentration, although a plot of log ionic strength vs Tm deviates from lin...
متن کاملEngineering Hcp1 to Bind DNA
Current deoxyribonucleic acid (DNA) processing methods used for DNA sequencing and microarray analysis rely on restriction enzymes that produce oligonucleotides of heterogeneous lengths. Homogenous length DNA would be an advantage to chip based DNA analysis technologies as a way to reduce false positives (incorrect matches of complementary DNA). Nanotubes of discrete lengths could serve as a te...
متن کاملThe DNA intercalators ethidium bromide and propidium iodide also bind to core histones
Eukaryotic DNA is compacted in the form of chromatin, in a complex with histones and other non-histone proteins. The intimate association of DNA and histones in chromatin raises the possibility that DNA-interactive small molecules may bind to chromatin-associated proteins such as histones. Employing biophysical and biochemical techniques we have characterized the interaction of a classical inte...
