An osmiophilic distyryl ditetrazolium salt (ds-nbt) for ultrastructural dehydrogenase activity
TL;DR: The preparation of a new osmiophilic ditetrazolium salt (DS-NBT) containing two styryl groups, but retaining the essential structural features of nitro-BT is given.

Photooxidation of diaminobenzidine (DAB) by chloroplast lamellae.
Izhak Nir,Arnold M. Seligman +1 more
TL;DR: It was of interest to see whether DAB would also act as an electron donor in some part of the chain of electron transport in photosynthesis, making it possible to study the localization of this reaction in ultrastructural preparations.
Ultrastructural localization of oxidase activities in corn root tip cells with two new osmiophilic reagents compared to diaminobenzidine
Izhak Nir,Arnold M. Seligman +1 more
TL;DR: The ultracytochemical potential of N,N'-bis(4-aminophenyl)-1,3-xylylene-diamine (BAXD) and BED as electron donors for plant oxidases was tested and compared to 3,3'-diaminobenzidine (DAB).

Visualization of intracellular concanavalin A binding sites in retinal photoreceptors.
TL;DR: The relationship between the localization of Con A binding sites and the orientation of visual pigment molecules within the rod outer segments disk membranes was discussed.

THE ULTRASTRUCTURAL LOCALIZATION OF CYTOCHROME c-OXIDASE COMPLEX IN A LIPID-RETAINING, GLUTARALDEHYDE-UREA EMBEDMENT'
Izhak Nir,Daniel C. Pease +1 more
TL;DR: Kidney tissue, incubated in a phosphate-sucrose buffer with diaminobenzidine (DAB), subsequently was embedded in polymerized glutaraldehyde-urea and retains lipids in ultrathin sections and thus permits a precise localization of reaction products in relation to cytomembranes.
