Application

Neocarraoctaose has been used in a study to assess sequence determination of sulfated carrageenan-derived oligosaccharides. It has also been used in a study to investigate the differential carbohydrate binding and cell surface glycosylation of human cancer cell lines.

Preparation Note

Prepared enzymatically from κ-carrageenan.

Other Notes

Mixed anomers

A kappa-carrageenase was isolated from the cell-free medium of cultured Pseudomonas carrageenovora. From dodecylsulphate/polyacrylamide gel electrophoresis, a single protein (identified as the kappa-carrageenase) was detected in the medium. Activity against nominal carrageenan types and inspection of the products indicate the
