A b s t r a c t The variation of silicate dissolution and crystallization rates with chemical affinity and solution composition can be quantified by the identification of the rate controlling precursor complex. The nature of this complex depends on the individual mineral structure. Specifically, the destruction of quartz and anorthite frameworks requires the breaking of only one type of structu...

We have investigated the binding of bepridil to calcium-saturated cardiac troponin C in a cardiac troponin C/troponin I complex. Nuclear magnetic resonance spectroscopy and [(15)N,(2)H]cardiac troponin C permitted the mapping of bepridil-induced amide proton chemical shifts. A single bepridil-binding site in the regulatory domain was found with an affinity constant of approximately 140 microM(-...

The epigenetic modification of 5-hydroxymethylcytosine (5hmC) is receiving great attention due to its potential role in DNA methylation reprogramming and as a cell state identifier. Given this interest, it is important to identify reliable and cost-effective methods for the enrichment of 5hmC marked DNA for downstream analysis. We tested three commonly used affinity-based enrichment techniques;...

Textile industry comprises of dry mechanical and wet chemical processing,wet chemical process comprises of bleaches, dyeing , printing, & finishing. Dyeing is art of colouration to textiles.Dye get transferred to textile during dyeing. Dyeing operation is performed by the reaction between fiber and dyes. Some dyes are water soluble and some are water insoluble. Some fiber has affinity to dye; s...

cdse nanostructures were synthesized by using green chemical route as starch was used as capping agent. xrd, hr-tem, sead, uv and pl studies were made for structural and optical properties of the prepared sample. film morphology and the thickness measurement of n-cdse were carried out with afm analysis. i-v characteristics curve of this junction confirmed the formation of schottky contact betwe...

Detecting a small molecular-weight compound by electrospray ionization mass spectrometry (ESI-MS) requires the compound to obtain a charge. Factors such as gas-phase proton affinities and analyte surface activity are correlated with a positive ESI-MS response, but unfortunately it is extremely challenging to predict from a chemical structure alone if a compound is likely to yield an observable ...

Central to the study of chromosome biology are techniques that permit the purification of small chromatin sections for analysis of associated DNA and proteins, including histones. Chromatin purification protocols vary greatly in the extent of chemical cross-linking used to prevent protein dissociation/re-association during isolation. Particularly for genome-wide analyses, chromatin purification...

We introduce MIP system and molecular imprinting technique to create synthetic receptor or binding sites for bio/chemical detection technology. Those binding sites in MIP’s system have specific molecular recognition functions for targeting specific chemical or bio-molecules. This study presents functional microfabrications using MIPs’ system to develop useful bioor chemical sensors/devices. We ...

Nucleic acid aptamers have minimal immunogenicity, high chemical synthesis production, low cost and high chemical stability when compared with antibodies. However, the susceptibility to nuclease degradation, rapid excretion through renal filtration and insufficient binding affinity hindered their development as drug candidates for therapeutic applications. In this review, we will discuss method...

In the present work, the quantum theoretical calculations of the molecular structure of the (N-(2-benzoylphenyl) oxalamate has been investigated and are evaluated using Density Functional Theory (DFT). The geometry of the title compound was optimized by B3LYP method with 6-311+G(d) basis set. The theoretical 1H and 13C NMR chemical shift (GIAO method) values of the title compound are calculated...
