This product is specially designed for soil DNA extraction, using silica gel column purification technology, combined with the original humic acid adsorbent technology, suitable for extracting high yield and high purity total DNA from various soils, such as forest soil, grassland soil, mining soil, sediment and other samples. Humic acid adsorbents can efficiently adsorb humic acid and other inhibitors in soil samples, and the purified DNA can be directly used in PCR, Southern hybridization, enzyme digestion and other experiments. This product is suitable for extracting high-purity DNA from soil samples less than 0.5 g. Product advantages: fast extraction, can complete the extraction of several samples in 40 minutes (after digestion); High purity, resulting DNA that can be used directly in a variety of downstream applications; Reproducible, silica column purification technology, and ideal results every time.
