Abstract A study was performed to discover what Geno/Grinder® processing variables significantly increased or decreased the yields of genomic DNA. Variables investigated included homogenization time and speed, while buffers, grinding media and tubes were constant. Comparison was done against another commercially available, cell lysing machine. In this experiment it was discovered that homogenization times of 90 seconds in the Geno/Grinder® at a speed of 2000 produces the best results. SPEXGENO 2010 高通量組織研磨機
