Disc electrophoresis of rat plasma lipoproteins.
The disc electrophoresis of lipoproteins of unfractionated rat plasma is described. The plasma was prestained with Sudan black B and electrophoretically separated at polyacrylamide gel concentrations of 7.5, 5, and 3.75%. At least four lipoprotein components were observed, and an additional 2-3 components in the main gel and 2-5 components in the spacer gel possibly were present. Densitometry o...
متن کاملEvaluation of diabetes-related short-chain organic acids in rat plasma by capillary electrophoresis.
A capillary zone electrophoresis method was optimised to analyse low-molecular-mass organic acids for the purpose of monitoring diabetes in rat plasma. The method included acetoacetic, 2-hydroxybutyric, lactic and uric acids. A variation in the background electrolyte allowed us to measure pyruvic acid in the same sample. Conditions have been optimised for measuring a large number of plasma samp...
متن کاملGradient gel electrophoresis of human plasma lipoproteins.
A rapid and simple method for separating and identifying plasma lipoproteins is described. The technique utilizes the “molecular sieving” properties of continuous concave gradient electrophoresis on a slab of polyacrylamide (4 to 26%) gel. Gradient gel electrophoresis is particularly suitable for separating lipoproteins according to their molecular weight. The technique can be used to demonstra...
متن کاملTwo-dimensional electrophoresis of human plasma apolipoproteins.
The two-dimensional electrophoretic method with silver staining we describe better resolves plasma apolipoproteins (apo) than any procedure previously described. It can be used to screen for abnormalities in apoA-I, apoA-II, apoA-IV, apoC-II, apoC-III, apoD, apoE, and apoH. In addition, this is the first presentation of apoD and apoH on two-dimensional gels. This electrophoretic method will per...
متن کاملStarch-gel electrophoresis of rat-serum proteins.
In 1955, Smithies (1) described a procedure for the separation of human serum proteins by horizontal zone electrophoresis in starch gels. The separation of zones was improved by a later modification to a vertical electrophoresis in which the sample was inserted in the gel, free from supporting medium (2). With these methods, it has been demonstrated that many more protein fractions can be separ...
