Microsatellite loci from the house wren (Troglodytes aedon)

We cloned seven microsatellite loci from house wrens (Troglodytes aedon) using a biotin enrichment protocol. Starting with fragments generated using DOP-PCR, fragments containing microsatellite motifs AC and AAC were captured using biotinylated probes and streptavidin coated magnetic particles. Captured fragments were cloned into plasmids; prior to sequencing, the plasmids were screened for microsatellites using a simple PCR approach. Five of the loci showed variation in a sample of nine individuals.
