Abstract

1. A new p-nitrophenyl substituted ditetrazole, 2,2'-di-p-nitrophenyl-5,5'-diphenyl-3,3'-(3,3'-dimethoxy-4,4'-biphenylene) ditetrazolium chloride (Nitro-BT), is introduced, which possesses most of the properties of an ideal reagent for histochemical purposes. It permits the cytochemical visualization of the sites of enzymic activity in tissue sections from 2-8 µ thick, under aerobic conditions, after a relatively short incubation period. 2. A comparison was made of the various tetrazoles in common use with several new p-nitro substituted analogues of these agents. 3. A survey was presented of the enzyme distribution in the major tissues of the rat and dog. Evidence for the reliability of cytochemical localization is provided by illustrative material in selected tissues. 4. The new tetrazole can be employed for the diphosphopyridine nucleotide and triphosphopyridine nucleotide diaphorase systems as well as for the succinic dehydrogenase system by substituting Nitro-BT for blue tetrazolium (BT) in the incubation media.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
