The product is used for the pretreatment of the sample to be tested by releasing the sample to be tested from the state of combining with other substances, which can facilitate the use of in vitro diagnostic reagents or instruments to test the substance. Special Formula: The preservation solution contains exclusive resin beads, which can efficiently absorb impurities in the sample and improve the purity of nucleic acid. Strong Adaptability: It can match the nucleic acid detection reagents of mainstream manufacturers on the market (Daan Gene, Sansure Biotech, Liferiver, BioGerm, BioPerfectus, etc.) Biosecurity: Effectively inactivate the virus,reduce sample contamination and ensure the safety of personnel. Extraction-Free: This productâ??s function combines sample collection and nucleic acid extraction, and the nucleic acid released from the sample can be directly amplified as a PCR template. Excellent Inhibitor Tolerance: The preservation solution does not contain guanidine salt and does not inhibit PCR reaction, ensuring smooth downstream reaction. Stable Storage: Can be transported at room temperature for at least 7 days
