Dye-Binding Method for Rapid Colorimetric Determination of the Cholestasis Charaterizing Lipoprotein-X
Serum lipoproteins were stained by the addition of Sudan Black B solution. The normal lipoproteins and the excess of Sudan Black were removed with heparin and zinc acetate solution. The abnormal lipoprotein-X remained in the supernatant, the blue colour of which was measured. The empirically obtained constant was used for calculation, thus avoiding standardization.Peer Reviewe
