A rapid and quantitative method for the isolation of gangliosides and neutral glycosphingolipids by DEAE-silica gel chromatography.
DEAE-silica gel has been shown to be an improvement over DEAE-Sephadex for the quantitative isolation of gangliosides and neutral glycosphingolipids from animal tissues or cells. Preliminary results indicated that it can also be used for protein separation. Direct comparative studies of DEAE-silica gel with DEAE-Sephadex showed preferences for the former for the following reasons: i) faster flow rate; ii) more rapid equilibration with the starting buffer; iii) easier regeneration; iv) more economical; and v) a lesser susceptibility to microbial attack.
