Sulforhodamine B Structural

What is Sulforhodamine B?

Chemical properties

This substance is a deep red powder. It is easily soluble in water, forming a bluish-red solution with yellow fluorescence. When sodium hydroxide solution is added, it also appears bluish-red. Additionally, it is soluble in ethanol. In concentrated sulfuric acid, it turns orange-yellow and red after dilution.

The Uses of Sulforhodamine B

Sulforhodamine B Sodium Salt is a rhodamine dye widely used in nonpermanent tattoos. Studies show that Sulforhodamine B can be used as a potential new therapeutic agent for the treatment of the acute respiratory distress syndrome. Dyes and metabolites, Environmental Testing

The Uses of Sulforhodamine B

Sulforhodamine B sodium salt has been used:

  • for relative total cell mass quantification
  • to investigate the viscosity of coacervates
  • as a molecular rotor for microviscosity determination in aerosol droplets

What are the applications of Application

Sulforhodamine B (SRB) is known for use in SRB assay for the determination of in vitro cytotoxicity through staining and the observation of live cells, proliferation and drug screening.
It has been used in the SRB assay to evaluate the effect of mouthwashes on protein content in primary cultures of human fibroblasts.
It is also suitable as a microscopic tracer for the assessment of blood-brain barrier integrity by post mortem inspection of frozen sections. SRB is useful as a caries detector dye with subsequent inspection of histological material.

What are the applications of Application

Sulforhodamine B sodium salt is a fluorescent rhodamine dye, widely used in nonpermanent tattoos and potentially as a new therapeutic agent.

Definition

ChEBI: Sulforhodamine B is an organic sodium salt having 4-[3,6-bis(diethylamino)-2,7-dimethylxanthenium-9-yl]benzene-1,3-disulfonate as the counterion.

Preparation

4-Formylbenzene-1,3-disulfonic acid and 3-(Diethylamino)phenol condensation, the products with sulfuric acid dehydration, and ferric chloride oxidation, and finally into sodium salt.

General Description

Sulforhodamine B (SRB) is a bright-pink aminoxanthene dye. The sulforhodamine B (SRB) assay is extensively used for in vitro cytotoxicity screening. SRB binds to the protein constituents of the cells in a stoichiometric manner. Thus, the amount of dye extracted from stained cells is directly proportional to the cell mass. SRB can also be used for cell density determination.

Flammability and Explosibility

Not classified

Biochem/physiol Actions

Sulforhodamine B sodium salt is useful to measure cell biomass and also for cytotoxicity screening.
