Determination of Lipoproteins by Paper Electrophoresis

A reproducible technic is presented for the staining of lipoproteins on paper. This method gives a greater total uptake of dye than previously described procedures, especially by the α-lipoproteins. The staining is accomplished with a solution of Sudan Black B in a mixture of methyl and isopropyl alcohols and the excess dye is removed by wash solution of 30% isopropanol.
