摘要:

用鸡的微卫星引物对6个中国地方鸡种的两个微卫星位点进行PCR扩增。将扩增产物在变性与非变性聚丙烯酰胺凝胶(PAGE)上进行电泳,经银染,表明微卫星产物在二者上的电泳结果有明显的差异。在非变性聚丙烯酰胺凝胶中,表现为有较多的非特异带,而在变性胶中微卫星扩增产物条带清晰,易于鉴定。Abstract:The genomic DNAs from six chicken breeds in China were amplified using two microsatellite primers. The PCR products were detected by non-denatured and denatured PAGE gels respectively, and the gels were dyed by silver. There were distinct differences between the two kinds of gel. In non-denatured gels. There were many nonspecific bands while clear purposed bands were showed in denatured gels.
