The microsatellite loci from Cervus nippon sinchuanicus genome was isolated by Streptavidin-coated Magnetic Beads Adsorption method. The length of 200~750 bp DNA fractions containing microsatellite sequences were captured by oligonucleotide probes. The enriched DNA segments were ligated on pMD18-T and then transformed into E. coli JM109 competent cells. Then PCR was applied to screen positive clones from the libraries. All 234 positive clones were identified from 576 transformants. As a result, 73 sequences were acquired. Besides (CAG)n, (AG)and (AT)n repeat sequences were also obtained. The results indicated that the method was efficient to isolate microsatellite markers. The markers will be useful tools for further studies on C. n. sinchuanicus genetics and genomics.
