In general, for the histochemical demonstration of peroxidase , b enzidine, naphthol, and leuco-dyes are utilized in the prosence of hydrogen peroxide. Among these , the technical modifications of the benzidine-peroxide method are the most numerous . Alpha-naphthol has been used less often than benzidine . Application of the leucodye method for animal tissues is remarkably limited and this meth...

Nano fertilizers are new products which contain readily available nutrients in the nano scale range and are preferred largely due to their efficiency. This research was conducted to assessment the effect of nano chelated of micro nutrient on agronomic traits of Cowpea via factorial experiment based on randomized complete block design with four replications during 2016 seasonal year. The treatme...

The title compound, C(16)H(12)Cl(2)O, was synthesized from 1-naphthol and 1,2-dichloro-benzene with anhydrous aluminium chloride as a cataylst. In the mol-ecule, the two ring systems are approximately perpendicular to one other with a dihedral angle of 82.06 (4)°. There are two CH-type hydrogen bonds.

This experiment was designed to investigate the effects of different levels copper–methionine chelates and alfalfa powder on egg yolk cholesterol content, quality, performance in laying hens. In this experiment, a total 100 hens (Nick Chick strain, from 109 117 weeks age) were arranged into five experimental treatments, consisting 2 dietary copper chelate (2x2) factorial completely randomized d...

Excess di(tert-butyl)silylene (DTBS) bis(trifluoromethanesulfonate) formed bis-DTBS derivatives with the four aldopentoses (arabinose, lyxose, ribose and xylose). The structure of the bis-chelates was affected by the bulk of the DTBS groups and the requirement of flat silacycles in the case of five-membered chelate rings. These restrictions resulted in unusual cyclic bis-chelates for ribofurano...

The authors demonstrate herein a novel time-resolved fluoroimmunoassay (TRFIA) protocol for quantification of human IgG with the new bifunctional chelate Eu(TTA)₃(5-NH₂-phen) (ETNP) labeling the goat anti-human IgG. The immunoassay was conducted by following the typical procedure for sandwich-type immunoreactions. Goat anti-human IgG was immobilized on aldehyde-modified glass slides. The human ...

One factor that is critical to the potential effectiveness of radioimmunotherapy is the design of radiometal-chelated antibodies that will be stable in vivo. Stability in vivo depends on the condition that both the chelate linkage and radiolabeling procedures not alter antibody specificity and biodistribution. In addition, synthesis and selection of the chelating agent is critical for each radi...
