An X-ray crystal structure of Kelch-like ECH-associated protein (Keap1) co-crystallised with (1S,2R)-2-[(1S)-1-[(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)methyl]-1,2,3,4-tetrahydroisoquinolin-2-carbonyl]cyclohexane-1-carboxylic acid (compound (S,R,S)-1 a) was obtained. This X-ray crystal structure provides breakthrough experimental evidence for the true(More)
An immunoassay readout method based on surface-enhanced Raman scattering (SERS) is described. The method exploits the SERS-derived signal from reporter molecules that are coimmobilized with biospecific species on gold colloids. This concept is demonstrated in a dualanalyte sandwich assay, in which two different antibodies covalently bound to a solid(More)
Three forms of nano-trititanate (H(2)Ti(3)O(7) nanomaterial) were prepared by a hydrothermal method to replace nano-TiO(2) for sterilizing the environment. The bactericidal capabilities of these nano-trititanates were observed to be more significant compared to nano-TiO(2) both with and without exposure to UV light. For the future commercial applications of(More)
The open-tubular electrochromatographic (OT-CEC) migration behavior of a series of peptides, based on a common structural feature, has been characterized using two different types of chemically modified etched capillaries. The organic moieties immobilized onto the capillary inner surface were n-butylphenyl and cholesterol-10-undecenaoate, respectively. The(More)
Two sets of peptides, each having structurally similar amino acid sequences, have been investigated by capillary electrochromatography (CEC) using etched chemically modified capillaries as the separation medium. In comparison to gradient RP-HPLC, the resolving power of the described CEC methods has been found to be superior. A number of variables have been(More)
An extensive survey of the properties and separation capabilities of a cholesterol bonded phase is reported. The intermediate hydrophobic/hydrophilic properties of the bonded cholesterol material allows this stationary phase to be used for both reversed-phase and aqueous normal-phase separations. Interesting high selectivity is reported for the structural(More)
Tungsten oxide nanorods were prepared from commercial crystalline WO(3) particles treated with triethylamine under electron beam irradiation in an electron microscope operating at 200 kV. The amine acts as a molecular knife, cleaving the particles under beam irradiation.
