Handling Instructions Technical Support

Pyronin Y (Pyronine G) is a cationic dye that intercalates RNA and has been used to target cell structures including RNA, DNA and organelles. Pyronin Y forms fluorescent complexes with double-stranded nucleic acids (especially RNA) enabling semi-quantitative analysis of cellular RNA. Pyronin Y can be used to identify specific RNA subspecies of ribonuclear proteins complexes in live cells.

제품 설명

Pyronin Y (Pyronine G) is a cationic dye that intercalates RNA and has been used to target cell structures including RNA, DNA and organelles. Pyronin Y forms fluorescent complexes with double-stranded nucleic acids (especially RNA) enabling semi-quantitative analysis of cellular RNA. Pyronin Y can be used to identify specific RNA subspecies of ribonuclear proteins complexes in live cells[1][2][5].

In Vitro

Pyronin Y forms fluorescent complexes with double-stranded nucleic acids, especially RNA, enabling semi-quantitative analysis of cellular RNA in flow cytometry, to estimate the RNA content per cell in formalin fixed EL4 leukosis tumor cells, enzyme dispersed R3327-G rat prostatic adenocarcinoma cells, mouse spleen cells stimulated with concanavalin A, and human peripheral blood lymphocytes stimulated with phytohemagglutinin[1].
Pyronin Y is almost entirely localized in the mitochondria of cultured cells in living cells. At concentrations of 1.7 to 3.3 μM, it is non-toxic but inhibits cell growth, causing cell arrest[3].
Pyronin Y has long been used, in combination with other dyes such as Methyl Green, as a differential stain for nucleic acids in paraffin tissue sections. In sections stained with Methyl Green-pyronin Y, red blood cells, elastic fibre of blood vessels, zymogen granules of pancreatic acinar cells, surface membrane of heptocytes and kidney tubular cells showed strikingly strong green and/or red fluorescence, while the nuclei of cells appeared non-fluorescent[4].
Pyronin Y binds to double stranded RNA (dsRNA) including messenger RNA (mRNA), transfer RNA (tRNA) and ribosomal RNA (rRNA)[5].

Cell Assay 
[2]

The cells are resuspended and stained for 30 min in 1.0 mL of 0.01% pyronin Y in sodiumacetate buffer (1.0 M, pH 4.7). For this purpose 1.0 g of pyronin Y is dissolved in 100 mL distilled water and this solution is purified by chloroform extraction (three fractions of 100 mL). The purified pyronin Y solution is diluted with 1.0 M sodiumacetate buffer pH 4.7 to the appropriate concentration and filtered through paper filters before use. Stained cell samples are studied by fluorescence microscopy (excitation filters SP 560 and LP 515, chromatic beam splitter at 580 nm, barrier filter LP 580) or by flow cytometry[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
