With the increasing demand for nucleic acid testing projects, the need to purchase virus preservation solutions is also increasing. The components of the virus preservation solutions are: Hanks solution base, gentamicin, fungal antibiotics, BSA (V), cryoprotectant , Biological buffers and amino acids, etc.
The virus preservation solution is suitable for the collection, preservation and transportation of common virus samples such as new coronavirus, influenza virus, hand, foot and mouth virus. Pharyngeal swabs, nasal swabs or tissue samples of specific parts can be collected, and the stored samples can be used for subsequent clinical experiments such as nucleic acid extraction or purification.
The cell preservation solution is a general-purpose cell cryopreservation solution, which can be used to freeze human and various animal cell lines; the complete cryopreservation solution formula is ready to use, convenient and fast; non-program cooling, -80℃ low-temperature refrigerator freezing It can be stored for up to 5 years to ensure the safety of cryopreserved cells; perforated plates (cell culture plates) can be used for cryopreservation of hybridoma cells. The cell preservation solution has a diluting effect, which can separate a large number of effective cells embedded in the mucus, so that more cells of test value can be preserved, and provide a sufficient number of cells to ensure the accuracy of the test results; at the same time, after processing After low-speed centrifugal filtration of the sample, the mucus in the sample can be completely removed, effectively preventing the mucus from interfering with the sample test results. The cell preservation solution can be made into a uniform monolayer cell sheet after low-speed centrifugation, which meets the inspection requirements.
Except for professionals, many people tend to confuse the cell preservation solution with the virus preservation solution, thinking that the two refer to the same kind of preservation solution. In fact, the cell preservation solution is mainly used to freeze cells, while the virus preservation solution has some There are two types of inactivated and non-inactivated types. The inactivated type is mainly used for nucleic acid detection. For example, the more popular new coronavirus nucleic acid detection is the inactivated virus storage solution, and the non-inactivated type is mainly used for The biggest feature of virus culture and reproduction is that it can provide more accurate test results.
