Many tumor-associated and leukocyte-associated carbohydrate antigens function as adhesion molecules recognized by lectins, (carbohydrate-protein interaction) or complementary carbohydrates (carbohydrate-carbohydrate interaction). Common structures are found in the tumor-associated and leukocyte-associated antigens. Metastatic potential of tumor cells as well as transendothelial migration of leukocytes was suppressed by agents or combinations of, agents of the groups: (a) carbohydrate antigens; (b) antibodies directed to those antigens; (c) oligosaccharide components of those antigens; (d) conjugates of the antigens or oligosaccharides; and (e) mimetics of the antigens or oligosaccharides. …

Why it's free to use
- Filed February 19, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 19, 2013.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
