The persistence of the new crown epidemic has brought a lot of opportunities and challenges to the whole IVD industry chain. In the whole industry chain, there are many enterprises dedicated to the research and production of virus preservation solution, which has been recognized by the market and made great contributions to the epidemic.
Virus sampling tube consists of which parts
Virus sampling tube by the swab + sampling tube + virus preservation fluid three parts composition. The virus preservation solution consists of Hank's liquid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer and amino acids. On top of Hank's base, virus stabilizing components such as 4-hydroxyethylpiperazine ethanesulfonic acid (HEPES) and BSA (fifth component of bovine serum albumin) are added to maintain virus activity over a wide temperature range, reduce the rate of virus decomposition, and enhance the positive rate of virus isolation.
Precautions for use of virus preservation solution
(1) It is forbidden to directly contact the collected person with the preserved solution in which the virus sample has been placed.
(2) It is forbidden to moisten the swab with the preservation solution before sampling.
(3) This product is disposable and is intended only for the collection, transport and preservation of clinically collected virus specimens and should not be used beyond its intended use.
(4) The product should not be used after the expiration date or if the product packaging is damaged.
(5) The collection of viral specimens should be carried out by professionals in strict accordance with sampling procedures, and specimens for testing should be operated in laboratories that meet safety standards.
(6) Specimens should be transported to the corresponding laboratory within 3 working days after collection, the preservation temperature of 2 ~ 8 °C; if not sent to the laboratory within 72 h, should be stored at low temperature, and specimens should avoid repeated freezing and thawing.
What are the advantages of Shenzhen Huarui Kang's virus preservation solution?
Complete range: We can provide inactivated and non-inactivated virus preservation solution, and we can also provide product trial service.
Stable nature: stable products with little batch variation.
Price advantage: compared with other virus preservation solution manufacturers, the quality is more guaranteed and there is more room for concessions.
Shipping speed: Always in stock and fast delivery of original stock.
Technical service: equipped with a professional team of more than ten years to provide technical support.
The quality of virus preservation solution is the key factor to improve the positive rate of PCR detection and positive rate of virus isolation, which fundamentally determines the quality of virus sampling tubes. The addition of room temperature stable fungal antibiotics can solve the problem of mold contamination after sampling and realize the room temperature preservation of the sampling solution.
