Empirical Bioscience recently introduced its Plasmid Mini-Prep Kit. The kit requires only 1 to 3 mL of bacterial culture, and isolates for extraction high-quality plasma or cosmid DNA up to 10 kb in length with yields of up to 20 µg per preparation. The kit also features an integrated pH indicator within the lysis buffer. This indicator changes color to bright yellow when the lysis buffer reaches 7.5, the optimal pH level for DNA binding. If the pH is greater than 7.5 the lysis buffer will appear orange or violet in color indicating that the pH level is inefficient for DNA adsorption, allowing researchers to make adjustments to the mixture for more efficient plasmid isolation.
