Ma. Kadhim et al., An improved micro-method for obtaining chromosome preparations from individual haemopoietic colonies, BR J HAEM, 105(3), 1999, pp. 673-675
A robust method for obtaining chromosome preparations from individual haemo
poietic colonies in semisolid media is described. The accumulation of metap
hases and the hypotonic treatment of cells were carried out in the culture
dish and individual colonies were transferred onto poly-L-lysine-treated sl
ides and fixed stepwise prior to staining. The technique produced high yiel
ds of well-spread metaphases facilitating clonal cytogenetic analysis.
