Restriction enzyme banding of mouse metaphase chromosomes

Abstract
Fixed metaphase chromosomes from mouse strain RIII embryos or A9 cells were treated with a restriction endonuclease, followed by Giemsa staining. Aha I, Hinf I, or Mbo I treatment produced a C-band pattern, and Eco RII or Hae III produced a G-band plus C-band pattern. Ava II and Bst NI each produced a G-band pattern, but on most chromosomes only a small segment of each C-band, adjacent to the centromere, was stained. These tiny residual C-bands may contain a minor satellite located adjacent to the major satellite clusters.
