| Abstract: | In this experiment,hircine blood genomic DNA was extracted,nested primer was designed by AMEL gene of goat,and the concentration of the DNA was tested by Ultraviolet spectrophotometer,then blood genomic DNA of goats was serially diluted(10-2μg/μL,10-3 μg/μL,10-4μg/μL,10-5 μg/μL),and nested PCR amplification was tested by Agarose gel electrophoresis.The results show that the method of nested PCR using 10 pg genomic DNA(approximately 3 cells),could get clear purpose band.The method based on sex identification by nesred PCR amplifying amelogenin gene was highly accurate and sensitive.There is an important significance about sex identification before embryo transfer and enhancing the survival rates of cutting embryo transplantation by using ultratrace DNA detection. |
