| Abstract: | The distribution of anti-RNA antibody-binding sites on the surfaces of Ehrlich ascites tumor cells was studied by membrane immunofluorescence after binding anti-RNA antibody on the cell surfaces. Results showed that the cells formed caps after incubation with anti-RNA antibody at 4 degrees C and the elevation of their temperature to 37 degrees C. Pronase treatment of the cell surfaces completely inhibited reactivity with anti-RNA antibody. These results suggest that the RNAs on the surfaces of Ehrlich ascites tumor cells are linked to membrane protein membrane-bound cytoskeleton complexes. |
