Abstract: | Homogeneous populations of human blood platelets or erythrocytes were lysed in alkaline EDTA, bound to nitrocellulose and hybridized to a radioactive mtDNA probe. By comparison to standards of known mtDNA concentration, we determined that platelets contained 4 mtDNA molecules per cell. Rhodamine 123 staining revealed an average of 4 mitochondria per platelet indicating that each mitochondrion contains a single mtDNA molecule. No detectable mtDNA was found in erythrocyte lysates. Using the same procedure, we found that in nucleated cells, mitochondria contained multiple mtDNAs per mitochondrion. |
