Abstract

We describe a sensitive, reproducible procedure of analysis for the six neutral carbohydrates in glycoproteins, by high resolution anion exchange chromatography. As many as 16 neutral carbohydrates can be separated by elution with a concentration gradient of boric acid (pH 7, 67 to 672 mmol/liter). The carbohydrates are detected with a cerate oxidimetric detector system, which monitors the fluorescence of the Ce3+ produced by the reaction of the eluted constituents with the Ce4+. Sensitivity to 1 nmol of fucose is demonstrated. Analytical methods and results are presented for mannose, fucose, and galactose in serum glycoproteins of both normal women and those with metastatic breast cancer. We briefly discuss the possibility of separating and analyzing for the three neutral carbohydrates in serum glycoproteins in 4 h by isocratic (constant eluent concentration) elution from a chromatographic column.
