| pubmed-article:7462190 | pubmed:abstractText | The amount of S-II, a protein specifically stimulating RNA polymerase II, was measured in various mouse organs by a micro complement fixation assay. The amount was almost the same in brain, liver, kidney, spleen, and Ehrlich ascites tumor cells on the basis of DNA, being about 3.8 micrograms/mg DNA, which corresponds to 3.6 X 10(5) molecules/cell. However, the amount of S-II decreased greatly during erythro-differentiation of Friend leukemia cells and no S-II was detected matured erythrocytes. | lld:pubmed |
