Thermo Scientific™ Orange G 85+%, pure, high purity

Thermo Scientific™ Orange G is a high-purity, water-soluble azo dye used primarily as a biological stain in histological and molecular biology applications. With ≥85% dye content, this orange to orange-red powder offers excellent performance and reliability for staining proteins, cytoplasm, and nucleic acids in both research and teaching laboratories.

Commonly employed in protein electrophoresis (e.g., SDS-PAGE), histology, and chromosome banding, Orange G binds selectively to structures such as acidic protein residues and cytoplasmic components. It is also a component of complex staining formulations like the Papanicolaou stain and serves as a tracking dye in gel electrophoresis due to its distinct migration behavior.
