Seventeen cosmid clones that corresponded to the STSs were successfully isolated. Single-color fluorescence in situ hybridization (FISH) using the 17 cosmids as probes, 11 were mapped to the expected regions of 11q. Then, the order of localization of the 7 cosmids (cG20, cG38, cG38R, cG50, cG51, cG75 and cR54) at the 11q21-q22.3 region were determined by two-color FISH on the extended prometaphase chromosomes, as cen-cG50-cG75- cG51-cG38-cG38R-cG20-cR54-tel. The result not only confirmed that microdissection is useful in the isolation of region-specific DNA clones, but also indicated that subsequent single- or two-color FISH is a valuable tool to map novel clones and marker DNAs, especially their order in the human genome., Acta medica Nagasakiensia. 1996, 41(3-4), p.26-30}, pages = {26--30}, title = {Mapping and Ordering Cosmid Clones Obtained from Human Chromosome Region 11 q 13.4-q25 by Fluorescence in situ Hybridization}, volume = {41}, year = {1996} }
