Diagnosis of dyslipoprotein aemia by molecular sieve chromatography.
Agarose gel molecular sieve chromatography has been used as a tool in the diagnosis of dyslipoproteinaemias. The elution profile from control plasma contained three peaks, corresponding to very-low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). These accounted for 9.5%, 23.5% and 67% of the total lipoprotein absorption at 280 nm. Elution patterns from dyslipoproteinaemic serum showed alterations, not only in peak area, but also in peak migration rate through the agarose gel. These variations were reproducible and of such magnitude as to permit the use of molecular sieve chromatography as a tool in the diagnosis of dyslipoprotein-aemias of Type I, II (a + b), III, IV and V.
