Methylene blue Methylene blue(methylthioninium chloride) (MB) is a cationic colorant from the phenothiazines family, is a tricyclic phenothiazine, soluble in water and some organic solvents, over the years it has been used as a treatment for malaria, methemoglobinemia, among other pathologies. Th...
The methylene blue (MB) method for glycosaminoglycans (GAGs) assay is commonly used because of its sensitivity and convenience. The basis of the assay method is the binding of dye to GAGs, with production of a dye-GAGs complex which absorbs decrease at 664 nm, but the mechanism of the ...
On day 14, the MTT assay was performed. During this two-week incubation period, we noticed the skin tissues treated with high concentrations of MB (5.0 μM and above) started to appear blue after 3 days, suggesting that MB dosage needs to be limited to avoid its colorant side effect ...

The methylene blue (MB) decolorization assay was based on the analysis of spectral profiles of dye in interaction with a different bacterial concentration. The determination of dye decolorization rate (DDR) shows a correlation between the MB reduction rate and the bacterial density. Moreover, the ...
Quantitative estimation using Photometric titration The application provides a method to determine assay of methylene blue using photometric titration by exploiting its redox properties. 拨打电话询价 Download Application Background Methylene blue is a commonly used dye that exhibits array of biological propert...
The results of this study add insight to the spectrum of features of MB within the central nervous system and may be helpful for understanding the molecular mechanisms underlying a potential therapeutic effect of MB. 展开 关键词: Adult stem cells Alzheimer’s disease methylene blue neural ...
