Brilliance Yang Cell Preservation Solution

Test principle of cell preservation solution:

Potassium, sodium ions for the cells to provide the required nutritional 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, preserving 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, preserving the integrity of proteins 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 index of Brilliance Yang cell preservation solution:

The cell preservation solution is colorless and transparent liquid. The surface should be smooth, flat and clean, and there should be no deformation, dirt or leakage of liquid
The capacity 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 in the cell preservation solution, the cell morphology should be intact, no obvious contraction, swelling.
The use of cell preservation solution:

Before sampling, mark the relevant sample information on the label of the sampling tube
Sample with a sampling swab (or sampler).
After sampling, quickly put the sampling swab into the sampling tube with cytosolic preservation solution, break the part above the sampling tube (or put the sample collected by the collector into the sampling tube with cytosolic preservation solution and mix it well), and screw the cap tightly.
Caution:

This product is for in vitro diagnostic use only
After collecting a cell sample with a 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 the preparation of the sample, the amount of sample can be increased appropriately.
Sampled samples must be fresh and fixed in time to avoid cell autolysis.
