This is usually achieved by treating cells with tubulin inhibitors, such as colchicine or demecolcine (colcemid), that depolymerize the mitotic spindle and so arrest the cell at this stage. Excessively long incubations with Colcemid result in overcondensed chromosomes that band poorly and moreover some cell type...
