General description

The Griess reagent is used for the quantitative analysis of nitrite ions. Present nitrite (as well as nitrate) ions will form a pink diazo dye by diazonium coupling reaction with N-(1-Naphthyl)ethylenediamine. The concentration of nitrite (or nitrate) ions is proportional to the color intensity of the resulting red solution.

Pancreatic islets and insulinoma cells are particularly vulnerable to serious damage by cytotoxic nitric oxide (NO) and/or oxidative stress, most probably due to their low expression levels of antioxidant enzymes. This cellular damage has been regarded as one of major

Spontaneous Regression/Complete Resistant (SR/CR) mice are a colony of cancer-resistant mice that can detect and rapidly destroy malignant cells with innate cellular immunity, predominately mediated by granulocytes. Our previous studies suggest that several effector mechanisms, such as perforin, granzymes, or

It has been proposed that the induction of cellular immunity and resistance to intracellular pathogens is dependent upon CD40 ligand (CD40L). In the present study we show that this proposal is not ubiquitously supported. Mice genetically deficient in CD40L (CD40LKO)

The Emu-TCL1 transgenic mouse spontaneously develops a CD5(+) B cell lymphoproliferative disorder similar to human chronic lymphocytic leukemia (CLL). Given the ineffectual T cell antitumor responses in this mouse model of CLL, we sought to determine whether combined treatment with

Using two-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis, we found that copper/zinc superoxide dismutase (Cu/Zn-SOD, SOD-1) was induced in constructed CCR5 stably transfected HEK 293 cells, but not in mock cells, treated with CCL5. CCL5-induced SOD-1 expression was also confirmed in
