Yariv reagent (1,3,5-tri(p-glycosyloxyphenylazo)-2,4,6-trihydroxybenzene) is a glycosylated phenolic compound that binds strongly to galactans and arabinogalactan proteins.[1][2][3] It can therefore be used in their detection, quantification, precipitation, isolation, staining, and interfere with their function.[3][4] It was initially synthesised in 1962 as an antigen for carbohydrate-binding antibodies but has subsequently become more broadly used.[1][5] There are many variants of Yariv reagents which vary in the glycosyl groups on the outside of the structure, typically glucose, galactose, and mannose.[6]

A biographical article about Joseph Yariv was published by the Journal of Applied Crystallography. [7]
