Three tetrazolium salts are used as histochemical indicators of dehydrogenase activity in the skin of sheep and other mammals. Of these compounds 2-(p-iodophenyl)-3-(p-nitrophenyl)-5-phenyl-tetrazolium chloride (INT) is shown to be the most satisfactory. It enables various histological structures of the wool follicle to be conveniently demonstrated.. In the presence of appropriate substrates and DPN and ATP, the intracellular deposition of the granular formazan in frozen sections has revealed the distribution of succinic, α-glycerophosphoric, lactic, and malic dehydrogenases, and regions where some phosphorylated carbohydrate intermediates promote reduction. Metabolic activity in the Malpighian layers and in the undifferentiated epidermal cells of the hair matrix reduces INT enzymatically up to the pre-keratinous zone. Here the protein-bound sulphydryl groups reduce INT and produce intense red staining which is easily distinguished from the granular enzymic staining.. The distribution of ...

XTT assay is a colorimetric method that uses the tetrazolium dye, 2,3-bis-(2-methoxy-4-nitro-5-sulphenyl)-(2H)-tetrazolium-5-carboxanilide (XTT) to quantify cell-mediated damage to fungi. Actively respiring fungal cells convert the water-soluble XTT to a water-soluble, orange colored formazan product (Meshulam et al., 1995). Here, we describe the protocol that measures the ability of plasmacytoid dendritic cells (pDCs) to exert antifungal activity. This approach was first established with human polymorphonuclear cells (PMN) by Meshulam et al. (1995) and then adapted to pDC by Ramirez-Ortiz et al. (2011) and Loures et al. (2015). It can be modified for use with other effector cells and to test compounds for antifungal activity., XTT测定是使用四唑鎓染料，2,3-双 - （2-甲氧基-4-硝基-5-磺酰基） - （2H） - 四唑鎓-5-甲酰苯胺（XTT）定量细胞介导的损伤的比色法 到真菌。 主动呼吸真菌细胞将水溶性XTT转化为水溶性橙色甲an产物（Meshulam等人

Since heterotrophic prokaryotes play an important biogeochemical role in aquatic ecosystems and have a high capacity to survive in extreme environments, easy-to-perform protocols that probe their physiological states and the effects of environmental variables on those states are highly desired. Some methodologies combine a general nucleic acid stain with a membrane integrity probe. We calibrated one of these, the nucleic acid double-staining (NADS) protocol (G. Gre ́gori, S. Citterio, A. Ghiani, M. Labra, S. Sgorbati, S. Brown, and M. Denis, Appl. Environ. Microbiol. 67:4662-4670, 2001), determining the optimal stain concentrations in seawater and the response to conditions that generate prokaryote death (such as heat) and to conditions that are known to produce death in plankton, such as nutrient limitation or flagellate grazing. The protocol was validated by comparison to two methods used to detect viability: active respiration by 5-cyano 2,3-ditolyl tetrazolium chloride (CTC) and ...

Various assays, using different strategies, are available for assessing cultured cell proliferation. These include measurement of metabolic activity (tetrazolium salts and alamarBlue), DNA quantification using fluorophores (Hoechst 33258 and PicoGreen), uptake of radioactively-labeled DNA precursors such as [3H]thymidine, and physical counting (hemocytometer). These assays are well established in characterizing cell proliferation in two-dimensional (2D), monolayer cultures of low cell densities. However, increasing interest in 3D cultures has prompted the need to evaluate the effectiveness of using these assays in high cell density or 3D cultures. We show here that typical cell proliferation assays do not necessarily correlate linearly with increasing cell densities or between 2D and 3D cultures, and are either not suitable or only rough approximations in quantifying actual cell numbers in a culture. Prudent choice of techniques and careful interpretation of data are therefore recommended when ...

Breast cancer is one of the deadliest forms of cancer and is the second most common cause of death for women after lung cancer. Many potential drugs do not work well due to the resistance and complexity of the molecular pathways that trigger the growth and division of breast cancer cells, highlighting the need for continuous urgent exploration of drugs and molecular targets in breast cancer. The objective of the present study is to determine the potential use of Flavopereirine in controlling breast cancer. Breast cancer cells were exposed to the varying concentration of drug along with negative control to analyze the effect of the drug on cancer cell viability. We have found a 5 micromolar concentration of Flavopereirine to inhibit about 50% cell viability using XTT assay. Thereafter, cells were grown with drug and whole cells were harvested to analyze the effect of the drug on gene expression. RNA from the drug-treated and control cells was isolated, followed by cDNA synthesis. We have ...

A stable reagent for assaying an analyte from a fluid sample which includes an enzyme, a mediator, a tetrazolium salt and an oxidizing agent selected from the group consisting of sodium chlorate, 2,5-dimethylhexane-2,5-dihydroperoxide, benzoyl peroxide, t-butyl peroxide, sodium iodate, N-ethylmaleimide, t-butylperoxyacetate, nickel acetylacetonate, stannic chloride, rhodium (III) trichloride hydrate, and t-butylperbenzoate is described. Inclusion of an oxidizing agent from the group specified above stabilizes the reagent, thereby preventing a high blank reaction because a high blank introduces error into the assay of an analyte. The reagent may be provided in solution form by adding water, or may be included in a film by adding a film-forming agent. The reagent may be utilized to perform the assay of an analyte from a fluid sample. The assay may be conducted in a solution medium by adding the fluid sample to the liquid reagent, and spectrophotometrically measuring absorbance of the color indicating the

Ellingsrud, Elisabeth; Wibrand, F.; Almaas, Runar; Dalen, Ingvild; Lindstad, Julie K. & Rootwelt, Terje (2005). Acidosis during reoxygenation has an early detrimental effect on neuronal metabolic activity. Pediatric Research. ISSN 0031-3998. 57(4), s 488- 493 . doi: 10.1203/01.PDR.0000155946.8223 Vis sammendrag We recently showed that acidosis is protective during hypoxia and detrimental during reoxygenation. We hypothesized that the detrimental effect of acidosis during reoxygenation was due to a negative effect on mitochondrial function. Human postmitotic NT2-N neurons were exposed to 3 h of hypoxia and glucose deprivation and then reoxygenated for 0, 1, 4, 9, or 21 h. The detrimental effect of acidotic reoxygenation on metabolic activity was evident already after 1 h of reoxygenation, when MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide] reduction (percentage of normoxic controls) was significantly higher in cells reoxygenated with neutral compared with acidotic medium ...

CARVALHO, Tereza Cristina de; KRZYZANOWSKI, Francisco Carlos; OHLSON, Osvaldo de Castro and PANOBIANCO, Maristela. Tetrazolium test adjustment for wheat seeds. J. Seed Sci. [online]. 2013, vol.35, n.3, pp.361-367. ISSN 2317-1537. https://doi.org/10.1590/S2317-15372013000300013.. The assessment of the germination test in wheat seeds varies from 4 to 15 days, because the species normally presents dormancy in freshly harvested seeds. The tetrazolium test can characterize seed viability in less than 24 hours including lots with dormancy seeds. The objective of this study was to develop a practical and efficient procedure for evaluating the viability of wheat seeds using the tetrazolium test. Five seed lots of the BRS 208 cultivar were used, where the following were tested: a) pre-conditioning between moist paper towels or direct immersion in water for 18 hours, at 20 °C; b) longitudinal section of the embryo and the endosperm; c) coloration on paper or by immersion for 2 and 3 hours, at 30 and 40 ...

View more ,PURPOSE: Artificial materials such as dental implants are at risk of bacterial contamination in the oral cavity. Human beta defensins (HBDs), small cationic antimicrobial peptides that exert a broad-spectrum antibacterial function at epithelial surfaces and within some mesenchymal tissues, could probably help to reduce such contamination. HBDs also have protective immunomodulatory effects and have been reported to promote bone remodeling. The aim of this study, therefore, was to investigate the influence of recombinant HBD-2 on the proliferation and survival of cells in culture. MATERIALS AND METHODS: Human mesenchymal stem cells (hMSCs), human osteoblasts, human keratinocytes (control), and the HeLa cancer cell line (control) were incubated with recombinant HBD-2 (1, 5, 10, or 20 姯mL). Cell proliferation and cytotoxicity were evaluated via a water-soluble tetrazolium salt (WST-1) and lactate dehydrogenase assays, respectively. RESULTS: HBD-2 was not toxic in any tested ...

Introduction In the present study, confocal microscopy, a miniflow cell system, and image analysis were combined to test in situ the effect of antimicrobials and alkali on biofilms of Enterococcus faecalis, Lactobacillus paracasei, Streptococcus anginosus, and Streptococcus gordonii isolated from root canals with persistent infections. Methods Biofilms formed for 24 hours were exposed for 5 minutes to alkali (pH = 12), chlorhexidine digluconate (2.5%), EDTA (50 mmol/L), and sodium hypochlorite (1%). The biofilms were then characterized by using fluorescent markers targeting cell membrane integrity (LIVE/DEAD) and metabolic activity (5-cyano-2,3-ditolyl tetrazolium chloride and fluorescein diacetate). In addition, the biofilm architecture and the extent to which coating of the substrate surface with collagen influenced the resistance pattern to the chemicals were also analyzed. Results NaOCl (1%) affected the membrane integrity of all organisms and removed most biofilm cells. Exposure to EDTA (50 ...

Purpose: : Oxidative damage to the Retinal Pigment Epithelium (RPE) is thought to play a major role in the development and progression of Age-related Macular Degeneration (AMD). The purpose of this in vitro study was to evaluate the ability of the selective 5-HT1A agonist, AL-8309A, to protect RPE cells against oxidative damage and to define the mechanism of the cytoprotective action. Methods: : Using the human RPE cell line ARPE-19, we have developed an in vitro survival assay using the cytotoxin 7-ketocholesterol (7kCh). Oxidative damage and apoptosis is induced by the addition of 7kCh, and the tetrazolium salt, WST-1, is used to assess cell viability following treatment. AL-8309A was evaluated in this model at concentrations from 0.01 nM to 100 µM. Western analysis was performed to assess changes in protein concentration and activation state in response to treatment with AL-8309A. The selective 5-HT1A antagonists, NAN-190 and WAY 100635, and specific Mek inhibitor, U0126, were used to ...

This study investigated the interaction between eupatorin and bovine serum albumin (BSA) using ultraviolet-visible (UV-vis) absorption, fluorescence, synchronous fluorescence, circular dichroism (CD) spectroscopies, and molecular modeling at pH 7.4. Results of UV-vis and fluorescence spectroscopies illustrated that BSA fluorescence was quenched by eupatorin via a static quenching mechanism. Thermodynamic parameters revealed that hydrophobic and electrostatic interactions played major roles in the interaction. Moreover, the efficiency of energy transfer, and the distance between BSA and acceptor eupatorin, were calculated. The effects of eupatorin on the BSA conformation were analyzed using UV-vis, CD, and synchronous fluorescence. Finally, the binding of eupatorin to BSA was modeled using the molecular docking method.

METHODS AND RESULTS Twenty-one dogs with 3 hours of left anterior descending coronary artery occlusion and 2 to 3 hours of reflow were studied. MCE was performed at 15 and 45 minutes and 2 and 3 hours after reflow. It was also performed at either 2 or 3 hours after reflow in the presence of 0.56 mg/kg of dipyridamole. Radiolabeled microsphere-derived blood flow was measured at 15 minutes and 2 and 3 hours after reflow and during dipyridamole effect. Infarct size was measured at the end of the experiment by use of triphenyl tetrazolium chloride. MCE data were processed with color-coding schemes that highlighted differences in myocardial videointensities in proportion to the concentration of microbubbles within the microvasculature. There was significant variability in MCE-defined perfusion patterns after reflow, with contrast defects noted mainly within the endocardium. There were fair and significant (P , .05) correlation (r = -.73 to r = -.55) between MCE defect size and normalized endocardial ...

Cell culture and toxicity studies. The HT-22 hippocampal nerve cell line is a subclone of HT4 (Morimoto and Koshland, 1990). The HT-22 clone was selected for its sensitivity to glutamate toxicity. The cells do not possess active ionotropic glutamate receptors and are not subject to excitotoxicity (Maher and Davis, 1996). HT-22 cells are propagated in DMEM (Vogt and Dulbecco, 1963) supplemented with 10% fetal bovine serum. Cell survival was determined by the MTT [3-(4,5-dimethyldiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay as described (Schubert et al., 1992), which in this cell system, correlates with cell death as determined by trypan blue exclusion and a colony-forming assay (Davis and Maher, 1994). Briefly, HT-22 cells are dissociated with pancreatin (Life Technologies, Gaithersburg, MD) and seeded onto 96-well microtiter plates in 5% dialyzed fetal bovine serum at a density of 2.5 × 103 cells per well in 100 μl of medium. The next day cells are treated with various reagents ...
