Abstract

A goat Bacterial Artificial Chromosome (BAC) library of 61,440 independent clones was constructed and characterized. The average size of the inserts was estimated at 153 kilobases by analyzing almost 500 clones using Not1 digestion followed by FIGE (Field Inverted Gel Electrophoresis) analysis. The library represents about three genome equivalents, which yields a theoretical probability of 0.95 of isolating a particular DNA sequence. After individual growth, the clones were arrayed in 40 superpools, which were organized in three dimension pools. A rapid technique for pool DNA preparation by microwave treatment was set up. This technique was compatible with PCR analysis. Primer pairs from 166 sequences (microsatellites, coding sequences from goat, and conserved Expressed Sequence Tags (ESTs) from humans) enabled the library to be successfully searched in 165 cases, with an average of 3.52 positive superpools. Only one sequence could not be found. The degree of chimerism was evaluated by FISH analysis with DNA from over 110 clones and was estimated at 4%. This BAC library will constitute an invaluable tool for positional cloning in ruminants, as well as for more general comparative mapping studies in mammals.
