Concentrate iodixanol gradient ultracentrifugation fractions with 10kDa filter?

16 July 2020 0 7K Report

Hi,

Can I concentrate iodixanol gradient ultracentrifugation fractions with a 10kDa filter?

Iodixanol is about 1550 g/mol (= 1.55 kDa?), so it should work, but I've tried with 3kDa and did not work for those iodixanol fractions with higher density (=more iodixanol)?

Thanks!
