Virus preservation solution (inactivated type) using high concentration of guanidine can quickly inactivate and preserve respiratory pathogens, so that the sample lost infectivity.Inactivated samples can be matched with a variety of viral DNA/RNA extraction kits, M32/96 nucleic acid extraction apparatus for rapid nucleic acid extraction, and respiratory pathogen PCR detection kit for rapid detection, the specificity and sensitivity are not affected.
Virus preservation fluid has many functions:
1. The operation is simple, no liquid distribution is needed, the system contains highly effective virus lysate, the virus is immediately inactivated after sampling, and the risk of secondary infection is effectively prevented.
2. Contain nucleic acid Rnase enzyme inhibitor, protect the viral nucleic acid from degradation to a greater extent, and greatly improve the efficiency of nucleic acid extraction.
3. The product can be stored at room temperature for 12 months before sampling, and the sample can be stored at room temperature for one week after sampling, with good tightness, which is convenient for storage and transportation and saves transportation cost.
In addition to the above inactivated virus preservation solution, there are also non-inactivated virus preservation solution, which contains Hanks fluid base, gentamicin, fungal antibiotics,BSA (V), cryoprotectants, biological buffers and amino acids.A variety of antibiotics combined with anti-bacterial and anti-fungal effects;Bovine serum albumin (BSA), as a protein stabilizer, can form a protective film in the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus.The neutral environment constructed by the Hanks buffer helps to increase the survival time and infection stability of the virus.Non-inactivated virus preservation solution is usually used for collection and transportation of clinical influenza, avian influenza (such as H7N9), hand, foot and mouth disease, measles and other virus specimens, as well as mycoplama, ureaplasa, chlamydia and other specimens.
