Abstract

The cellular location of the group D antigen was examined by fractionation of protoplasts prepared by digestion of cell walls with lysozyme in an osmotically protective medium. The major portion of the group D antigen appears to be closely associated with the protoplast membrane of ( 9790). Some antigen was found in the supernatant fluid (lysozyme hydrolysate) after removal of the protoplasts. This was attributed to the known fragility of protoplasts and membranes.
