A New Electrophoresis Technique to Seperate Microsatellite Alleles Vol.8 (11), pp.2432-2436. African Journal of Biotechnology. Interpretive Summary: Traditional agarose and polyacrylamide gel electrophoresis have been used commonly for microsatellite (simple sequence repeats, SSRs) analysis, but they are labor- intensive and not always able to provide accurate sizes for different alleles. Capillary sequencers provide automated analysis and accurate allele sizes; however, the costs of the instrument, reagents and labeled primers make the use of sequencers uneconomical for most routine microsatellite analysis. Here, we report a fast, cost-effective and accurate method for doing routine microsatellite array analysis using a compact, bench-top multi-capillary electrophoresis system, the HDA-GT12 TM Genetic Analyzer (eGene, Irvine, CA, USA). SSRs from flowering dogwood (Cornus florida L.) were used to compare the different types of electrophoresis.
