Sentence examples for dna complex and from inspiring English sources

This multimeric ssDNA then serves as a template for multiple reverse primers to hybridize, extend, and displace downstream DNA, generating a large ramified (branching) DNA complex, and resulting in an exponential amplification.

A selected region of the 2D 1heteronuclearuclear single quantum coherence correlation (HSQC) spectrum for free MA and the same region for MA in complex with a 16 mer DNA (Fig. 1B) is shown in Fig. 2. The 1HN/15N chemical shift differences between MA in the DNA complex and free MA mainly involve a loop region between residues 22 and 32 (Fig. 3A).

Groove binding agents are known to disrupt the transcription factor DNA complex and consequently inhibit gene expression.

DB244 also has strong contributions from molecular interactions in its DNA complex and all of these factors combine to give it the largest −ΔG° for binding.

We conclude that combination of cationized dextran plasmid DNA complex and 3D tissue engineered scaffold was promising to promote the in vitro gene expression for MSC.

MCO (0.4 µM FeCl3, 10 mM DTT, 100 mM Ethanol and 2 mM H2O2) was added to the protein DNA complex and the reaction was further continued for 30 min. The reaction was terminated by the addition of 10 mM EDTA, phenol extracted and analyzed on a 1% agarose gel in 1× TAE at 7 V/cm for 30 minutes.

The cells were incubated in the presence of DNA alone or DNA complexes for 4 h and further 44 h after the removal of DNA or DNA complexes, and then observed by fluorescence microscope.

Consequently, it has been demonstrated that the interactions between various DNA complexes and GAGs are far from identical.

Figure S9 shows how similar most dendrimer complexes were in the stability of their DNA complexes and DNA unloading capabilities, dissociating at only slightly different heparin concentrations.

In recent years, several glycosyl indolocarbazole derivatives have been developed as antitumor agents targeting the topoisomerase I-DNA complex and a few of them were evaluated in clinical trials.

DNA band disappears when the NP/DNA ratio is 1 16, indicating complete formation of the complexes and that the NPs have good ability to bind negative DNA. Figure 1 Agarose gel electrophoresis of plasmid NP-DNA complex and corresponding three-dimensional projection plot of band intensities.
