Nomenclature for Plasma Lipoproteins

According to their electrophoretic mobility in supporting media, e.g., paper, agarose, or cellulose acetate, serum lipoproteins can be defined as pre-)8, j8-, and ai-lipoproteins, grossly corresponding to VLDL, LDL, and 

respectively. By starch block, some of the VLDL exhibit 0 2-mobility, whereas by polyacrylamide gel electrophoresis the pre-j8 band migrates in post-)8 position, a phenomenon due to the sieving effect of the supporting medium.
