Comparison of three analytical methods for superoxide produced by activated immune cells
Publication date: Available online 31 October 2019Source: Journal of Pharmacological and Toxicological MethodsAuthor(s): Zhixiang Zhu, Ran Guo, Yunqian Li, Shanshan Li, Pengfei TuAbstractSuperoxide plays a key role in normal immune function and inflammatory diseases. In order to evaluate normal immune function or screen inhibitors of superoxide production for treating inflammatory diseases, it is very important to detect superoxide with good accuracy, sensitivity, and flexibility. In present study, we investigated three analysis methods of superoxide, colorimetric assay by WST-8, fluorescence assay by dihydroethidium and c...

Precipitation of test chemicals in reaction solutions used in the amino acid derivative reactivity assay and the direct peptide reactivity assay
Publication date: Available online 22 August 2019Source: Journal of Pharmacological and Toxicological MethodsAuthor(s): Yusuke Yamamoto, Sayaka Wanibuchi, Ayako Sato, Toshihiko Kasahara, Masaharu FujitaAbstractThe Amino acid Derivative Reactivity Assay (ADRA) was developed by the authors as an in chemico alternative to animal testing for skin sensitization potential. Although ADRA is based on the same scientific principles as the Direct Peptide Reactivity Assay (DPRA), a comparison of the results from these two test methods shows a far lower incidence of precipitation of test chemicals in reaction solutions for ADRA than f...

A label-free approach to detect cell viability/cytotoxicity based on intracellular xanthine/guanine by electrochemical method
In this study, an electrochemical method for detecting cell viability and cytotoxicity was discussed with the intracellular small molecule metabolite purines as indexes.MethodsThe electrochemical behaviors of Balb/c 3T3, CHO, PC-12 and V79 cell suspensions were studies by cyclic voltammetry, and cell viability and cytotoxicity of four cell lines were compared by electrochemical, cell counting, 3-(4,5-dimethyl-2-Thiazyl)-2, 5-diphenyl-2H-tetrazolium bromide (MTT) and trypan blue exclusion methods.ResultsFour cell lines all showed an oxidation peak derived from mixture of xanthine and guanine at about 0.7 V. Using intracel...
