<p>A method of readily measuring lipid-bound sialic acid (LSA), and useful in screening tests for cancer, comprises mixing a LSA separating agent comprising a polar solvent with a sample containing LSA and other forms of sialic acid, separating precipitate formed to obtain a supernatant, and measuring the lipid-bound sialic acid concentration of said supernatant by using an enzyme capable of acting on sialic acid in a lipid-bound state to yield a fragment determinable by a colourimetry technique. A reagent kit for use in such method is proposed.</p> |
