title: Acid glycosidase and arylsulfatase activities of human cerebrospinal fluid as measured by concanavalin A-sepharose affinity chromatography.
abstract: An affinity chromatographic method using concanavalin A-Sepharose is described for the determination of N-acetyl-beta-D-glucosaminidase, arylsulfatase. alpha-L-Fucosidase and alpha-D-mannosidase activities in the human cerebrospinal fluid. By this method (starting with 12 to 20 ml samples of cerebrospinal fluid) the above enzymes could be obtained in a concentrated form and their activities could be determined within incubation periods of 30 min to 1 h under the assay conditions described. The pH optima of the enzymes were in the range of pH 4 to 5. About 80% of the total cerebrospinal fluid N-acetyl-beta-D-glucosaminidase was found to be the A form by DEAE-Sephadex A-50 chromatography. About 60% of the total arylsulfatase was also found to be the A form. Determination of these enzyme activities in a few samples of human cerebrospinal fluid indicated a rough proportionality between the enzyme activities and the protein concentration in the cerebrospinal fluid.
