Plasma lipids and lipoproteins of some members of the order Perissodactyla

1. Percentage low density ( ) and high density ( ) lipoproteins in the plasma Cellulose acetate electrophoresis Analytical ultracentrifuge lipoprotein lipoprotein LDL HDL White rhino n=5 100 - 100 - Black rhino n=1 100 - 100 - Indian rhino n=1 100 - 100 - Cellulose acetate electrophoresis In the Rhinocerotidae only one peak was seen on Cellulose acetate electrophoresis, the mobility of which would characterize it as lipoprotein. Similar patterns were observed in all specimens. Analytical ultracentrifuge In the Rhinocerotidae, there was a complete absence of the HDL characteristic of the Equidae. The LDL was of complex composition usually composed of two peaks, one having a flotation rate similar, and one slower, than that of human LDL. The Indian and black rhinos had very similar patterns to the white rhino, although in the Indian rhino there was more of the slower moving band. 2.
