Approximately 40% of the clones contain repetitive sequences. Of 48 single copy clones tested, 26 (54%) hybridized to chromosome 2. Constructed by microdissecting fragments from 20 chromosomes, treating with proteinase K, extracting with phenol, ligating to an MboI linker-adaptor, amplifying by PCR, digesting with MboI, and ligating to pUC19. |
