Web2 mrt. 2024 · Slides containing metaphase spreads with EdU-labeled SCEs were pre-selected and used for oligo-FISH. Depending on the cytoplasm background, the slides were incubated in 45% acetic acid at RT for 10 min and washed in 2× SSC at RT for 10 min or directly post-fixed with 4% formaldehyde in 2× SSC at RT for 10 min.

Web29 apr. 2015 · Using metaphase spreads from human lymphoblastoid cell lines, we previously showed how immunofluorescence microscopy could define the distribution of histone modifications across metaphase chromosomes. We showed that different histone modifications gave consistent and clearly defined immunofluorescent banding patterns. … Webmetaphase stage of mitosis. The techniques for chromosome preparation are based on obtaining sources of dividing cells to produce high quality metaphase spreads with good … Webmosomal aberration defined “a” found in 16 metaphase spreads, a minor pattern of additional chromosomal aber-ration defined “b” found in one metaphase spread, and other two metaphase spreads with 47 and 48 chromosomes. As the result, this case presents four CAVs with “a,” “b,” and the two unknown patterns. As the second example, physics ipe
