摘要
Using degenerate primer amplification of chromosomes microdissected from banded cytogenetic preparations, we constructed both whole chromosome painting probes for mouse Chromosomes (Chrs) 1, 2, 3, and 11 and a centromere probe that strongly paints most mouse centromeres. We also amplified a Robertsonian translocation chromosome microdissected from unstained preparations to construct a painting probe for Chrs 9 and 19. The chromosomes probes uniformly painted the respective chromosomes of origin. We demonstrated the utility of the Chr 11 probe in aberration analysis by staining mutants that we had previously identified as containing a Chr 11 translocation, and in some mutant cell lines we observed chromosome rearrangements not previously detected in stained cytogenetic preparations. The technology of microdissection and amplification applies to all mouse chromosomes or to specific subchromosomal legions and will be useful in mouse genetics, in aberration analysis, and for chromosome identification.
