Now available in a pooled format for simultaneous analysis of large numbers of deletion strains through selective growth conditions. Identification and quantitation of the deletions surviving selection can be determined by hybridizing the deletions to a microarray containing all the barcode oligos. The barcode oligos are unique to each deletion, allowing rapid, high-throughput identification of the deletions. Each Yeast Deletion Pool contains all the deletions within the strain, equally represented within the pool. Yeast Deletion Pools are supplied in ten tubes, each containing 500 µl of the pooled deletions.
