| Popis: | The ratio of alpha- to beta-globin mRNA was measured by hybridization of a constant amount of highly purified alpha- or beta-globin cDNA (complementary DNA) with increasing amounts of RNA in the range up to 20% cDNA hybridization, where an essentially linear reaction is obtained. Statistical analysis indicates that the ratio of alpha- to beta-globin can be measured within a maximal error of +/- 0.3 and in most cases is better than +/- 0.15. Under these conditions there is no significant deviation from the ratio of 1.3 in the alpha- to beta-globin mRNA ratio of RNA isolated from erythroid cells rich in pronormoblasts through to reticulocytes. If the ratio of alpha- to beta-globin mRNA exceeded 1.7 or was less than 0.9 in pronormoblasts, it would be detected in these experiments. The overall globin mRNA content increases to a maximal value in the fractions rich in basophilic normoblasts of 30,000–50,000 molecules/cell. However, the accuracy of these determinations is not as great as for the ratio determinations, and no significant deviations were seen except in the cells rich in pronormoblasts, which contained less globin mRNA than the later stages. |
