Sequence-independent amplification and labeling of yeast artificial chromosomes for fluorescence in situ hybridization

摘要

We have developed a method that allows reliable construction of high quality FISH probes from yeast artificial chromosomes (YACs) based on the separation of YACs by pulsed-field gel electrophoresis and a rapid sequence-independent amplification procedure (SIA). These probes can be used to localize YACs on metaphase chromosomes and also with high efficiency, in interphase nuclei.
