The GenCatch® DEAE-silica anion exchange maxi column is a prepacked DEAE-silica gravity flow column specifically designed for plasmid purification. Its very large pore size and high density DEAE groups results in high binding capacity for plasmids. Combined with endotoxin removing buffer, it can product plasmids with very low endotoxin level (<0.1 EU/µg), unmatched by silica membrane based columns. GenCatch® DEAE-silica anion exchange column is also compatible with buffer sets from other manufactures such as Qiagen and Invitrogen. You can also make your own buffer according to our recipe.
