Pyronin Y(G) (PY) is a dye used for DNA staining. PY has orange spectral emission that is easily distinguishable from FITC and 7-AAD.
This dye has been used as a counterstain in saturated aqueous potassium alum and in a counterstain solution of 0.1% (w/v) with 5% aluminum sulfate for a Prussian Blue Stain for ferric iron. It has been used as a reagent for calcium in tissue where it forms a scarlet lake.
This “Mayer’s hemalum solution – for microscopy” is used for human-medical cell diagnosis and serves the histological and clinico-cytological investigation of sample material of human origin.
Immunofluorescence Quenching Solution is used in immunofluorescence and immunocytochemistry applications.
Cresol red is used as a tracking dye for DNA/RNA in agarose gel electrophoresis and protein in polyacrylamide gel electrophoresis.
