        The traditional method of collecting and extracting whole blood genomic DNA from human samples has several significant drawbacks: it requires specific blood collection equipment and trained medical personnel to complete; the pain of blood drawing leads to rejection and refusal of sampling; invasive collection increases the risk of infection; and blood samples must be transported and stored at low temperatures after collection.

        This kit provides a painless, non-invasive method for obtaining high-quality, high-quantity samples without the need for patients to endure the pain and risk of infection associated with blood drawing. It reduces the rejection rate of test subjects, making it convenient for both infants and the elderly to obtain DNA samples.

        The kit is suitable for extracting genomic DNA from saliva or various types of swab samples. It utilizes unique centrifugal columns and buffer systems, combined with efficient adsorption membranes that have the ability to selectively enrich DNA under certain conditions. When conditions change, DNA can be reversibly released, allowing for rapid purification and separation of DNA with maximum removal of impurities such as proteins, thereby ensuring the purity of the extracted nucleic acids.
