Direct method for measuring lipoprotein X in serum

Abstract

The authors describe a fast and easy method for routine quantitation of the abnormal lipoprotein, lipoprotein X. The procedure is based on densitometry of precipitation areas obtained for it after serum electrophoresis in agar gel followed by precipitation with polyanions. The coefficient of variation was less than 3% in one series. Results were linearly related to concentration in the range 0.063 to 6.3 g/liter.
