METHODS: Multiple microsatellite loci were simultaneously amplified by multiplex PCR. The products were electrophoresed on a Mega BACE capillary electrophoresis sequencer. The results were automatically analyzed by Genetic Profiler software. The effect of salt ion pair typing on the PCR system was observed at different times. Results The genotyping results of 10 loci in 96 samples were obtained by one-time PCR and electrophoresis, and the result of automatic typing was accurate and reliable. Its genotyping efficiency is twice that of plate electrophoresis. Conclusion Using capillary electrophoresis and Genetic Profiler automatic analysis software to carry out microsatellite genome scanning is efficient, saves manpower, effectively avoids human error, and is suitable for gene mapping, especially for the gene localization of multi-gene diseases, forensic medicine and human evolution .
