Elution profiles of wild-type and T15C virus-like particles from a Sepharose CL-4B column. The presence of coat protein in individual fractions was determined by SDS polyacrylamide gel electrophoresis followed by staining with coomassie blue and densitometry. Void volume is at fraction 11. A protein roughly the size of the coat protein monomer (lysozyme, MW about 14,000) elutes at position 33.
