Webpercentage of metaphase spreads were observed compared with the L15 group (Figure 2F; p = 0.021). Percentages of trials in which metaphase spread appeared showed a similar pattern to the percentage of metaphase spreads (Figure 2G). The proportions of normal diploid metaphase spreads in 30 samples were 43.3, 60.0 and 46.7% in L15F, …

WebMetaphase (from Ancient Greek μετα-() beyond, above, transcending and from Ancient Greek φάσις (phásis) 'appearance') is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most …
WebFirst, the PSCs are arrested in metaphase with colcemid. While FISH can be performed on intact, nonmitotic nuclei, the colce-mid treatment is often useful. Next, cells are trypsinized to a sin-gle cell suspension, swollen in a hypotonic solution, and fixed. Fixed cells are then dropped onto slides to make metaphase chro-mosome spreads.
