Chemically Specific Protein Immobilization Strategies on Analytical Surfaces
… of proteins after immobilization process. Using nitrilotriacetic acid (NTA) linkers and polyhistidine-tagged proteins, several synthetic strategies for presenting these linkers to the surface are illustrated. Gold was used as a primary surface. Data was also obtained for other potentially useful …

Multinuclear NMR Studies of Gallium Complexes in Aqueous Solution.
… with EDTA (ethylenediaminetetraacetate), NTA (nitrilotriacetic acid) and lactate etc. The results of these studies demonstrate that all the agents which inhibit in vitro gallium-67 uptake by L1210 leukemic cell also form complexes with the metal under various experimental conditions. The extent …

NON-FOULING AFFINITY PLATFORMS FOR PROTEIN IMMOBILIZATION IN ELECTRON MICROSCOPY
… non-fouling coatings bearing surface grafted nitrilotriacetic acid substituents that promotes specific capture of protein targets for high resolution TEM analysis. The utilization of these grids for specific adsorption of the targeted protein onto the grid surface results in well-controlled …

Chemically Induced Phytoextraction of Lead (Pb) Contaminated Soil by Switchgrass (Panicum virgatum L.), assisted with BAP and NTA applications
… the bioavailability of Pb. In the initial study nitrilotriacetic acid (NTA) 5mM, the alkylpolyglucoside (APG) Triton X-100 (2%), and nano-silica were applied to switchgrass (Panicum virgatum L.) growing in 5L pots of Pb-contaminated soil. The second experiment used 10mM NTA, the …

Synthesis and Cytotoxicity Studies of Gold Nanoparticle Systems
… such as carboxyl, hydroxyl, biotin and nitrilotriacetic acid (NTA) were introduced resulting in stable, biocompatible gold MPCs, templates for biomolecular functionalisation reactions. Biomolecular functionalisation strategies such as carbodiimide coupling, biotin-avidin interaction and …

Transition-Metal Complexes as Enzyme-Like Reagents for Protein Cleavage
… an inert complex with the N-terminal amino acid in the peptide. This binding is a prerequisite for subsequent cleavage, which occurs near these “anchoring” residues. We designed transition metal complexes for the cleavage of the first peptide bond downstream from the anchoring side chain of …

Trace metals in upper Susquehanna River ecosystem: environmental distribution, urban impacts, and interaction with sediment materials
… comparable to RW (5 7.5 and 3.0, RW + NTA [Nitrilotriacetic acid], synthetic seawater, and 1N Mg<sup>2+</sup> salt solutions. Release was low in neutral RW (Cd>Pb) and complete for many of the other systems. Sewage effluent samples contained micromolar levels of complexing agents, in excess …

Chemically Induced Phytoextraction of Lead (Pb) Contaminated Soil by Switchgrass (Panicum virgatum L.)
… (active ingredient propiconazole), the chelator nitrilotriacetic acid (NTA), and the phytohormones salicylic acid (SA) and benzylaminopurine (BAP) were tested on switchgrass grown in Pb contaminated soil from a former superfund site in Cedartown, GA. The soil chemical manipulation aimed at …

Identification of Novel Allosteric Regulators of Human Erythrocyte Pyruvate Kinase
… purification to a one step Ni-NTA (Nickel- nitrilotriacetic acid) column resulting in a 6-fold increase in the yield. Computational methods were applied to identify small molecules that bind to the allosteric activator fructose 1,6-bisphosphate (FBP) binding site of R-PK to identify …

Aspects of the chemistry of lead in multiphase soil model systems and the environment
… the manganese oxide (hausmannite) and humic acid phases were found to be responsible for most of this redistribution in both schemes. Despite the fact that both schemes allow severe Pb redistribution to occur, differences are apparent in the manner in which this occurs. Whereas Tessier et …

DEVELOPMENT OF CRISPR-CAS IMMOBILIZATION SRATEGIES FOR THE FABRICATION OF A BIOSENSING PLATFORM
… on the C-terminal portion of the Cas enzyme, the Nitrilotriacetic acid (NTA) chemistry, combined with bivalent cation activation, was investigated for the immobilization on the surface of tangential flow filtration (TFF) membranes and on magnetic silica beads. Extensive studies were conducted on …

Molecular recognition using nanotube-adsorbed polymer complexes
… from analytes such as dopamine, NADH, L-ascorbic acid, and riboflavin, d(AT)₁₅ imparts SWNT with a distinct selectivity toward NO. In contrast, the electrostatically neutral polyvinyl alcohol, enables no response to nitric oxide, but exhibits fluorescent enhancement to other molecules in the …

Organic complexation in karst cave systems: implications for transition metal incorporation into speleothems
… ligands in solution (Suwannee River Fulvic Acid (SRFA) and nitrilotriacetic acid (NTA)), however, the experimental calcite precipitates primarily depicted a direct inclusion of OMCs without prior dissociation. This was particularly pronounced for metal-SRFA complexes due to a considerable …
