A beta-D-galactosidase from bovine liver was purified to apparent homogeneity. The major purification step was affinity chromatography on a column of D-galactose attached to a Sepharose support activated with divinyl sulfone. Affinity media prepared by binding ligands to Sepharose activated

Two anthraquinone galactosyl-biomimetic dye-ligands comprising, as terminal biomimetic moiety, galactose analogues (1-amino-1-deoxy-beta-D-galactose and D(+)-galactosamine) were designed for the enzyme galactose oxidase (GAO), using molecular modelling, synthesized and characterized. The biomimetic ligands were immobilized on agarose beads and the affinity adsorbents

We have developed a new method for separation of antibody bound and unbound enzyme conjugates. The technique as applied to the assay of choriomammotropin involves the use of beta-D-galactosylamine bound to agarose to separate the unbound choriomammotropin-beta-galactosidase conjugates for antibody
The highly diastereoselective InCl(3)-catalyzed aza-Friedel-Crafts reaction of substituted indoles with aldimines generated from Kunz's amine was studied. The reaction afforded the desired product in good to high yields with up to >19:1 diastereoselective ratios. The O-pivaloylated beta-D-galactosyl moiety could not
