Abstract

Methods are provided for making rapid labeled dextran ladders and other calibrants useful in liquid chromatography. The methodologies include a two-step process comprising a reductive amination step of providing a reducing glycan and reacting it with a compound having a primary amine to produce an intermediate compound. The intermediate compound is then rapidly tagged with a rapid tagging reagent to produce the rapid labeled dextran ladder.
