On the "rapid beta" (Rbeta) lipoprotein variant of human serum
Abstract:
By visual inspection of agarose gel electrophoretograms of lipoproteins, a beta lipoprotein with increased mobility, here named "rapid beta" lipoprotein, has been observed. By objective measurements of the migration distances of the lipoprotein bands in 542 electrophoretograms by means of an exact ruler, this visual impression was objectively confirmed. In samples, classified by inspection as "rapid beta", the beta lipoprotein was found to have migrated approx. 20% further than in control samples. The "rapid beta" variant was initially detected in samples from grossly obese patients where it occurs frequently, but does not seem to be specific for any clinical abnormality.
