Description

Alizarin red S indicator (C.I. 58005) is a reductively active (quinone-based) anthraquinone dye that forms complexes with metal ions (such as zirconium, calcium) or boric acid to label calcium deposition and perform electrochemical sensing functions. Alizarin Red S undergoes reversible redox reactions (for electrochemical detection) and irreversible chelation (for bone staining). Alizarin Red S is mainly used in bone metabolism research (labeling mineralized tissue), sugar detection (boric acid-sugar competition system) and metal ion sensing (such as zirconium ion detection)， and can be used in osteoporosis and metabolic disease research[1][2][3].

In Vitro

Alizarin Red S (0.1 mM) is used as an electrochemical indicator in cyclic voltammetry. Through interaction with Phenylboronic Acid (HY-W001090) and the competitive effect of fructose, fructose is detected with a linear range of 50 mM[1].
Alizarin Red S (0.05 M; 5 min) is immobilized on a triacetylcellulose membrane after forming an ion pair with hexadecyltrimethylammonium bromide (CTAB) to construct a zirconium ion optical sensor. The detection range of Zr[4+] is 0.39-301 μg/mL, and the detection limit is 0.08 μg/mL[2].

* Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 1.25 mg/mL (3.65 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
