cell preservation solution

For the preservation and transportation of cells sampled from the human body for the purpose of in vitro analysis and detection only, not for therapeutic use.

Principles of testing cell preservation solutions:

Potassium, sodium ions for the cells to provide the required nutrient environment, the appropriate buffer energy can maximize the maintenance of the morphological integrity of the cells, so that they are fully suspended and dispersed. Ethanol can fix the cells, the structure of the virus, to preserve the cells, the virus form and avoid the cell not protease cleavage of cells and nucleic acid digestive enzymes on the digestion of nucleic acids, to preserve the integrity of the protein and nucleic acids for subsequent analysis. Anticoagulants are used to chelate heavy metal ions introduced into the solution to prevent cell coagulation. The ultimate goal is to maintain the integrity of cell morphology and nucleic acids in the preservation solution.

Product Performance Indicators for Cell Preservation Solution:

The cell preservation liquid is colorless and transparent liquid. The surface should be smooth, flat and clean, without deformation, dirt or leakage of liquid
The volume of each cell preservation liquid is 0.2ml/0.3ml/0.5ml/0.6ml/0.8ml/1ml/2ml/3ml/5ml/100ml.
The pH value of the cell preservation solution should be in the range of 7.0~7.6
Take oral cells, nasal cells and other samples placed in the cell preservation solution, the cell morphology should be intact, no obvious contraction, swelling.

How to use the cell preservation solution:

Before sampling, label the sampling tube with relevant sample information
Sample with a sampling swab (or sampler).
After sampling, quickly place the sampling swab into the sampling tube containing the cytosolic preservation solution, break the portion of the tube that is higher than the sampling tube (or put the sample collected by the sampler into the sampling tube containing the cytosolic preservation solution and mix it well), and screw the cap on tightly.
Caution:

This product is for in vitro diagnosis only
After collecting cell samples with the sampling swab, the head of the sampling swab should be completely immersed in the sample preservation solution to maximize cell retention.
If the amount of cells is found to be low during preparation, the sample volume can be increased appropriately.
The sampled sample must be fresh and fixed in time to avoid cell autolysis.
Note: This cell preservation solution is for in vitro diagnostic use, and cannot be used for internal or external use in humans or animals. If swallowed, it can lead to serious incidents; it is irritating to eyes and skin, if accidentally splashed into the eyes, flush with water. Ventilation should be maintained during use.
