Cell preservation solution”

Definition

Cell preservation solution is a special solution used to preserve cells, aiming to maintain the activity and function of cells and prevent cell death or damage. It usually contains various nutrients, buffers, cryoprotectants, and preservatives to provide a suitable environment.

Function

• Maintain cell viability: Provide necessary nutrients and energy to cells, maintain their metabolic activities, and extend their survival time.
• Prevent cell damage: Buffer solutions can stabilize the pH value inside and outside cells, preventing cell acidosis or alkalosis. Cryoprotectants can prevent cells from being damaged at low temperatures.
• Inhibit microbial growth: The addition of preservatives can inhibit the growth of bacteria, fungi, and other microorganisms, reducing the risk of cell contamination.
• Facilitate sample transportation: Allow cells to be transported at room temperature or low temperatures, facilitating the collection, transportation, and storage of samples.

Application

• Cytology research: Used to preserve cultured cell lines, primary cells, etc., for subsequent experimental research.
• Clinical laboratory: In medical laboratory tests, it is used to preserve cells in blood, urine, tissues, etc., for cytological analysis, pathogen detection, etc.
• Biobank: Cell preservation solution is one of the commonly used reagents in biobanks for long-term preservation of various cell samples.
• Vaccine production: In vaccine manufacturing, cell preservation solution can be used to preserve cells used for vaccine production, such as viruses or bacteria.

Different types of cells may require different preservation solution formulations, so it is necessary to select the appropriate cell preservation solution according to the characteristics of the cells and experimental requirements. At the same time, the correct preservation method and conditions are also crucial for the preservation effect of cells。
