BACKGROUND Microarray platforms will change immunochemical and nucleic acid-based analysis of cell homogenates and body fluids compared with classic analyses. Microarrays use labeled target and immobilized probes, rather than fixed targets and labeled probes. We describe a method for simultaneous labeling of nucleic acids and proteins. METHODS Horseradish peroxidase- and fluorescein-modified ...

Background: Recently, some new nanobiosensors using different nanoparticles or microarray systems for detection of mycotoxins have been designed . However, rapid, sensitive and early detection of aflatoxicosis would be very helpful to distinguish high-risk persons. Objectives: We report a highly sensitive competitive immunoassay using magnetic/silica core shell as a signal intensifier for the d...

Decomposition and nitrogen dynamics of 15N‑labeled leaf, root, and twig litter in temperate coniferous forests" (2013). USDA Forest Service / UNL Faculty Publications. Paper 253. patterns were species-specific. For multiple litter × species combinations, the difference between gross and net n mineralization was significant, and gross mineralization was 7–20 % greater than net mineralization. th...

Introduction: Many molecules can be labeled by iodine. Some of labeled substances are used for investigations of cancer treatment, biodistribution study in body, receptor binding, secrete pathway etc. Peptides are biomolecules and can be labeled by 131Iodine. ICD- 85 is a tri-peptide derived from Iranian brown snake venom and scorpion venom. This tri-peptide treats cancer by i...

The savannas (called Cerrado) are the second-largest vegetation formation in Brazil after Amazon rainforest, with about 2 million km2. Roots have been found very deep soil layers Cerrado ecosystems, which suggests a crucial role of rooting supply water and nutrients over dry periods. aim our study was to gain insight into complementarity common woody species taking up mobile throughout profiles...

When washed yeast cells grown under appropriate conditions were suspended in glucose solution there was a sudden release of alpha-amino nitrogen into the medium. This released material was of low molecular weight, and its composition was closely similar to that of the intracellular free amino acid pool. During the leakage of amino acids, the yeast did not efficiently absorb labeled amino acids ...
