In vivo staining with alizarin for ageing studies on chondrichthyan fishes

open access: yesAquatic Living Resources, 2020
Age determination for stock assessments and conservation of cartilaginous fishes is mainly obtained by counting the annual growth bands in vertebrae. Recent studies show numerous inconsistencies and the need for systematic validation.

Metal Complexes with Alizarin and Alizarin Red S: Electronic Absorption Spectra and Structure of Ligands

open access: yesRussian Journal of Coordination Chemistry, 2004
Most of the πl,π* bands of metal alizarinates are shown to be due to the 2,9- or 1,2-anthraquinoid structures. Bimetallic alizarinates with the 9,10-anthraquinoid structure are not formed because of the adjacent negatively charged oxygen atoms. The long-standing dispute concerning the structure of red metal alizarinates is solved: complexation always ...

Optimization of the Alizarin Red S Assay by Enhancing Mineralization of Osteoblasts

open access: yesInternational Journal of Molecular Sciences, 2022
The alizarin red S assay is considered the gold standard for quantification of osteoblast mineralization and is thus widely used among scientists. However, there are several restrictions to this method, e.g., moderate sensitivity makes it difficult to uncover slight but significant effects of potentially clinically relevant substances.

Spectrophotometric determination of ceterizine hydrochloride with Alizarin Red S

open access: yesTalanta, 1999
A simple, rapid and sensitive spectrophotometric method has been developed for the assay of ceterizine hydrochloride (CTZH) in bulk drug and its pharmaceutical preparations. This method is based on the ion-pair complex reaction between CTZH and Alizarin Red S in Clarks-Lubs buffer.

Voltammetric determination of boron by using Alizarin Red S

open access: yesAnalytica Chimica Acta, 2006
A novel voltammetric method for boron determination in ppb level is described. Boron complexes with Alizarin Red S (ARS) and the complex, as well as the free ligand, both adsorbs on a hanging mercury drop electrode. The method is based on the monitoring the anodic peak of the complex at -0.47 V in ammonium acetate-phosphate buffer (pH 7).
