Seed Coat Permeability Test: Tetrazolium Penetration Assay

open access: yesBio-Protocol, 2014
Seed coat permeability is important to study as it plays significant roles in seed dormancy, germination, and protection from pathogens. Here we describe a commonly used seed coat permeability test known as the tetrazolium penetration assay with a method

Extractive Spectrophotometric Determination and Theoretical Investigations of Two New Vanadium(V) Complexes

open access: yesMolecules, 2023
Two new vanadium (V) complexes involving 6-hexyl-4-(2-thiazolylazo)resorcinol (HTAR) and tetrazolium cation were studied. The following commercially available tetrazolium salts were used as the cation source: tetrazolium red (2,3,5-triphenyltetrazol-2 ...

Optimization of the Dose Rate Effect in Tetrazolium Gellan Gel Dosimeters

open access: yesGels, 2023
Tetrazolium salts provide an appealing candidate for 3D gel dosimeters as they exhibit a low intrinsic color, no signal diffusion and excellent chemical stability. However, a previously developed commercial product (the ClearView 3D Dosimeter) based on a
