SUMMARY Rabbit high density lipoprotein (HDL) has been isolated by ultracentrifugation, delipidated by ether and ethanol, and treated with urea prior to separation of the different polypeptides by gel nitration. The two different genetic polymorphisms known in rabbit HDL were found to reside in two different polypeptides. This conclusion was reached in experiments where a quantitative radial immunodiffusion technique was employed. The results of polyacrylamide gel electrophoresis in SDS indicate that the H1 1 antigen resides in a polypeptide chain with a molecular weight of 40,000, whereas the R 67 antigen resides in a chain with a molecular weight of 17,000.
