Product Description

Acid Red 92 ,Phloxine B for Biological stain

 

Specification:

Phloxine B (commonly known simply as phloxine) is a water-soluble red dye used for coloring drugs and cosmetics in the United States  nd coloring food in Japan. It is derived from fluorescein, but differs by the presence of four bromine atoms at positions 2, 4, 5 and 7 of the xanthene ring and four chlorine atoms in the carboxyphenyl ring.^[4] It has an absorption maximum around 540 nm and an emission maximum around 564 nm.Apart from industrial use, phloxine B has functions as an antimicrobial substance, viability dye and biological stain. For example, it is used in hematoxylin-phloxine-saffron (HPS) staining to color the cytoplasm and connective tissue in shades of red

Other names Cyanosin; Cyanosine; Eosine bluish; Eosine Blue; Cyanosin B; Eosin Blue; Phloxine P; Phloxin B; Eosine I Bluish; Acid red 92; C.I. 45410; D & C Red no. 28

Application

Phloxine B can be used to stain dead cells of several yeasts, including Saccharomyces cerevisiae and Schizosaccharomyces pombe. When diluted in yeast growth media, the dye is unable to enter cells because of their membranes. Dead yeast cells lose membrane integrity, so phloxine B can enter and stain the intracellular cytosolic compounds. Therefore, staining is a measure of cell death. In cell counting assays, the number of fluorescent (i.e. dead) cells observed through a haemocytometer can be compared to the total number of cells to give a measure of mortality. The same principle can be applied at higher throughput by fluorescence-activated flow cytometry (FACS), where all phloxine B-stained cells in a sample are counted.
