Description

Orange G (C.l. 16230) is the disodium salt of benzeneazo-2-naphthol-6,8-disulfonic acid, C16H10N2O7S2Na2. Orange G, also known as wool orange 2G, is a component in several industry applications including cytology, histology, biology, and industrial staining. It is a component of Mallorys connective tissue stain.Orange G is typically used as a background or cytoplasmic stain for various biological samples including a common application within clincial cytology within Papanicolaou varients.

Application

Propargyl-PEG4-acid serves as a versatile, bench-stable linker for bioconjugation and modular synthesis. Its terminal alkyne enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the carboxylic acid facilitates amide coupling or activation under standard conditions. The PEG4 spacer provides solubility and reduces non-specific binding, making it ideal for constructing functionalized probes, polymer architectures, and drug delivery systems with predictable reactivity and ease of purification.
