Preparation of Chromosome Suspensions

In this procedure, chromosomes are released from synchronized root tips mechanically after a mild fixation with formaldehyde. Chromosomes are released into a polyamine lysis buffer (LB01) which stabilises their structure. The method has been originally developed for chromosome isolation in field bean (Dolezel et al. 1992). Chromosome suspensions prepared according to this procedure are suitable for flow cytometric analysis and sorting.
