Studies on the Isolation of Metaphase Chromosomes
A method for the isolation of metaphase chromosomes from mouse L1210 leukemia cells has been developed. Cells, arrested at metaphase with colchicine, were exposed to hypotonic solution and the pH was then adjusted to 5.6 to stabilize the chromosomes. The metaphase figures were subsequently disrupted and the chromosomes isolated by a series of differential centrifugations in sucrose. The isolate...
متن کاملLocalization of mitotic factors on metaphase chromosomes.
The objective of this study was to determine whether the mitotic factors of HeLa cells, which induce meiotic maturation, i.e. germinal vesicle breakdown (GVBD) and chromosome condensation, when injected into fully grown Xenopus laevis oocytes, were localized in the cytoplasm or associated with the metaphase chromosomes. Cytoplasmic extracts were prepared by lysing mitotic HeLa cells in low-salt...
متن کاملNucleosomes in metaphase chromosomes.
Previous studies of the structure of metaphase chromosomes have relied heavily on electron micrography and have revealed the existence of a 10-nm unit fiber that is thought to generate the native 23-30-nm fiber by higher order folding. The structural relationship of these metaphase fibers to the interphase fiber remains obscure. Recent studies on the digestion of interphase chromatin have revea...
متن کاملIsolation of Metaphase Chromosomes from Hela Cells
The authors have developed a method for large-scale isolation of metaphase chromosomes from HeLa cells. The distinguishing feature of this method is the use of a pH sufficiently low (about 3) to stabilize the chromosomes against mechanical damage. Many milligrams of fairly pure, morphologically intact chromosomes can be isolated in 8 hr or less of total working time. The isolated chromosomes co...
متن کاملProteins of metaphase chromosomes and interphase chromatin.
Metaphase chromosomal and interphase chromatin proteins from cells of two species have been compared by polyacrylamide gel electrophoresis. Consistent, common changes in the quantitative distribution of the nonhistone chromosomal proteins are observed in both species. Proteins of ca. 65,000 and 68,000 MW are enriched in interphase chromatin while proteins of ca. 50,000 and 200,000 are more prom...
