General description

Ethylenediaminetetraacetic acid (EDTA) solution can be used to study cell biology, molecular biology, bioactive small molecules, biochemicals, solutions and reagents, inorganic salts, chelators and ethylenediaminetetraacetic acid (EDTA) and EDTA solutions.

Application

Ethylenediaminetetraacetic acid solution can be used to study cell biology, molecular biology, bioactive small molecules, biochemicals, solutions and reagents, inorganic salts, chelators and ethylenediaminetetraacetic acid (EDTA) and EDTA solutions. Ethylenediaminetetraacetic acid solution has been used in a study to help elucidate the role of antigen retrieval in immunostaining of ethanol-fixed smears. Ethylenediaminetetraacetic acid solution has also been used in a study to assess the uptake and release of biotin-labeled fluorescein (b-FITC) as well as immobilization of biotin-labeled glucose oxidase (b-GOx) to the polyelectrolyte microcapsules with an avidin-poly(styrene sulfonate) (PSS) membrane.

There has been much interest in the development of iron (Fe) chelators for the treatment of cancer. We developed a series of di-2-pyridyl ketone thiosemicarbazone (HDpT) ligands which show marked and selective antitumor activity in vitro and in vivo. In

Filarial nematodes cause chronic and profoundly debilitating diseases in both humans and animals. Applications of novel technology are providing unprecedented opportunities to improve diagnosis and our understanding of the molecular basis for host-parasite interactions. As a first step, we investigated

The endogenous lipid messenger oleoylethanolamide (OEA) inhibits eating and modulates fat metabolism supposedly through the activation of peroxisome proliferator-activated receptor-α (PPARα) and vagal sensory fibers. We tested in adult male rats whether OEA stimulates fatty acid oxidation (FAO) and ketogenesis

ABO incompatible living donor renal transplantation (ABOi) can achieve outcomes comparable to ABO compatible transplantation (ABOc). However, with the exception of blood group A2 kidneys transplanted into recipients with low titer anti-A antibody, regimens generally include antibody removal, intensified immunosuppression

Eosinophils natively inhabit the small intestine, but a functional role for them there has remained elusive. Here, we show that eosinophil-deficient mice were protected from induction of Th2-mediated peanut food allergy and anaphylaxis, and Th2 priming was restored by reconstitution
