摘要	A microsatellite-enriched library of plateau pika (Ochotona curzoniae) was constructed according to the strongaffinity between biotin and streptavidin. Firstly, genomic DNA was fragmented by ultrasonication, which is a majorimprovement over traditional methods. Linker-ligated DNA fragments were hybridized with biotinylated microsatelliteprobes, and then were subjected to streptavidin-coated magnetic beads. PCR amplificationwasperformedto obtain double-stranded DNA fragments containing microsatellites. Ligation and transformation werecarried out by using the pGEM-T Vector System I and Escherichia coli DH10B competent cells. Sequencing resultsshowed that 80.2% of clones contained microsatellite repeatmotif. Several modifications make this protocoltime-efficient and technically easier than the traditional ones; particularly,composition and relative abundance ofmicrosatellite repeats in plateau pika genome were truly represented through the optimized PCR conditions. Thismethod has also been successfully applied to construct microsatellite-enriched genomic libraries of Chinese hamster(Cricetulus griseus) and small abalone [Haliotis diversicolor (Reeve)] with high rates of positive clones,demonstrating its feasibility and stability.
