Transposon insertion site profiling chip (TIP-chip).

ABSTRACT: Mobile elements are important components of our genomes, with diverse and significant effects on phenotype. Not only can transposons inactivate genes by direct disruption and shuffle the genome through recombination, they can also alter gene expression subtly or powerfully. Currently active transposons are highly polymorphic in host populations, including, among hundreds of others, L1 and Alu elements in humans and Ty1 elements in yeast. For this reason, we wished to develop a simple genome-wide method for identifying all transposons in any given sample. We have designed a transposon insertion site profiling chip (TIP-chip), a microarray intended for use as a high-throughput technique for mapping transposon insertions. By selectively amplifying transposon flanking regions and hybridizing t
