The total viral nucleic acid extraction kit is suitable for extracting total viral nucleic acid from serum, plasma, tissue homogenate and other samples. The kit is based on silica column purification technology, which eliminates the need for toxic phenol-chloroform extraction and time-consuming alcohol precipitation. This product has successfully extracted nucleic acids from hepatitis B A/C, hepatitis C, and norovirus standard. The obtained DNA/RNA can be directly used in a series of downstream experiments such as PCR, RT-PCR, and LAMP.
