序列标签位点

以序列标签位点（STS）为路标构建重叠群图谱是目前最普遍、最经典、分辨率最高的物理作图方法。

The contig map basing on sequence - tagged sites ( STS ) is the most popular , the highest resolution physical map .

方法选取6个Y染色体特异性序列标签位点（STS），用PCR技术检测27例精子发生障碍患者AZF区微缺失情况。

Methods Six Y chromosome specific sequence-tagged-sites ( STS ) in AZF region were screened and the microdeletions were determined by PCR in 27 patients with spermatogenetic malfunction .

方法运用STSPCR法对25例无精症和27例严重少精症患者的Y染色体interval6的23个序列标签位点（STS）进行缺失筛查。

Methods Deletions in 25 azoospermic and 27 severe oligozoospermic Chinese patients were screened by STS PCR strategy . A total of 23 STSs in interval 6 of Yq , including 4 STSs in the deleted azoospermia gene ( DAZ ) region were analyzed .
