Abstract

A kit used for fractionation of small dense LDL cholesterol (sdLDL-C) in a sample, including: a first reagent composition having one or two or more activities selected from the group consisting of cholesterol esterase activity, cholesterol oxidase activity, and sphingomyelinase activity; and a second reagent composition for quantifying the sdLDL-C, in which in an absorption spectrum after storing the first reagent composition at 37° C. for 2 weeks, a ratio R1 represented by ABS400/ABS450 is 0.90 or more and 3.00 or less, and in an absorption spectrum after storing the second reagent composition at 37° C. for 2 weeks, a ratio R1 represented by ABS400/ABS450 is 0.90 or more and 8.00 or less.
