REDUCTION OF TETRAZOLIUM SALTS TO FORMAZANS IN FUSOBACTERIUM POLYMORPHUM

The Chemistry of Formazans and Tetrazolium Salts

ÖZ E T Bu çalışmada tetrazolyum tuzları ve formazanların yapıları tanımlanmıştır. Ayrıca formazan-tetrazolyum sistemlerinin önemi ve kullanım alanları açıklanmıştır. Formazanların sahip oldukları conjugate p-system kaynaklanan tautomerleşme özellikleri ve geometrik izomerleri incelenmiştir. Bu bileşiklerin en yaygın kullanılan sentezleri ve yapılarının açıklanmasında önemli olan UV-visible, IR ...

Fluorescent Formazans and Tetrazolium Salts - Towards Fluorescent Cytotoxicity Assays.

Formazan-based colorimetric cytotoxicity assays, such as the MTT assay, are typically used to assess cell viability with only metabolically active cells reducing tetrazolium salts into the formazans, which is then quantified by absorbance. Fluorescence offers several advantages compared to colorimetric assays and would enable techniques such as flow cytometry and confocal microscopy to be used ...

Reduction of tetrazolium salts by pleuropneumonialike organisms.

Tetrazolium salts have proved useful as indicators of electron transfer. Compounds such as triphenyltetrazolium chloride' are more practical than indicators like methylene blue since they are converted from a soluble colorless salt to an insoluble formazan in the reduced state. They also provide similar convenience in detecting enzymatic activity and specific sites of such activity (Bielig, Kau...
