Sampling swab 1 Oral or nasal swab + 1 bottle of 10ml virus DNA/RNA preservation solution (liquid volume:3ml)
The sampling swab shall be flocking swab. Compared with the conventional fiber swab, the sample is easy to be intercept- ed by the gap in the fiber cluster, that is, the sample is infiltrated, diluted and intercepted in the fiber. The flocking swab adopts the unique spray implantation nylon pile technology, which has outstanding sample collection and release ability, and the release rate can reach 90%, far higher than the fiber swab.
Composition and testing principle of virus preservation solution
The ingredients of the preservation solution are: Hanks solution, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids, etc.
A combination of antibiotics that have antibacterial and antifungal 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.
It is used for novel , avian influenza (H7N9), hand foot mouth disease(HFMD), measles and other viral specimens, as well as Mycoplasma, Ureaplasma , Chlamydia and other specimens collec- tion and transportation.
