Looking for a coloured weight marker (not blue dextran) for sepharose cL-2b gel column, MW around 3 kDa for separating fucoidan, suggestions pls?

22 May 2018 0 990 Report

I am trying to collect a fucoidan fraction of a known molecular weight as a substrate for some enzymes, I have packed a Sepharose CL-2B column and have a 2000 kDa blue dextran marker as the upper limit, I need a much smaller marker that is coloured (preferably not blue) and no less than 3 kDa, so that I could collect any fucoidan that is between 3 to 2000 kDa for analysis. Any suggestions please? Thanks!
