| Description
| - In this paper, we present a new method for homocysteine quantitation in human plasma based on in-capillary reaction of homocysteine with 2,2-dipyridyldisulfide. Homocysteine is in this so called thiol-exchange reaction quantitatively transformed in mixed disulfide concomitantly with formation of equimolar amount of 2-thiopyridone that is further separated by MEKC and determined specifically at 343 nm. The concentration of homocysteine is thus estimated indirectly from the result of 2-thiopyridone determination. The linear detection range for concentration versus peak area for the assay was from 0.03 to 3 mM (correlation coefficient 0.994) with a detection limit of 6 mM and a limit of quantitation 20 mM. The inter-day reproducibility of the peak area and the migration time were 1.37 % and 0.05 %, respectively. The method is simple, relatively rapid and can be easily automated. Moreover the common CE apparatus with UV detector can be used to distinguish between normal and pathological hyperhomocysteinem
