摘要：

A human supernumerary minichromosome (MC), found in a newborn baby and sorted on a fluorescence-activated cell sorter (FACS-440) has been previously described [Ferretti et al., Cytotechnology 1 (1987) 7-12]. We report here on the construction of a library of EcoRI fragments in the phage lambda-gtWES. lambda-B', starting from 7.5 ng of MC DNA, and describe the isolation of single-copy DNA clones from the library in a two-step procedure. We employed in situ hybridization to unambiguously select the clones specific for the MC, and used three of these clones to demonstrate that it originated from chromosome 9.
