This kit utilizes unique buffer system and spin column which can specifically bind to viral DNA/RNA,and is suitable for viral DNA/RNA extraction from 200 ??L whole blood/serum/gauze/saliva/swab/tissue homogenate and other samples. The silicon-based membrane in the Spin Columns GH3 is a unique material owned by our company. It efficiently and specifically adsorbs DNA/RNA and can effectively remove impurities such as protein. Extracted viral DNA/RNA has high purity, stable and reliable quality, and can be applied to various routine experiments.
