Yariv reactivity of β-galactans. β-Galactans resulting from single (β-galactan I), double (β-galactan II), triple (β-galactan III), and quadruple (β-galactan IV) Smith degradation of acacia gum were subjected to Yariv radial diffusion assay. The Yariv reactivity of β-galactan IV treated with FvEn3Gal is also shown. The average structures of the β-galactans are shown in Supplemental Figure S2. No reactivity toward α-Gal-Yariv was observed (Supplemental Fig. S1).
