What is the difference between tissue cryopreservation solution and cell cryopreservation solution, and which one is more effective?
Cell cryopreservation is a technique that involves storing living cells at low temperatures to maintain their viability, allowing them to be revived when needed. It is one of the primary methods for cell preservation, and cell cryopreservation solutions have a wide range of applications. In research, they are extensively used for cell storage, cell culture, and subculturing. Researchers can employ these solutions to preserve various cell types for future experimental use. Below, we will briefly introduce two commonly used cryopreservation solutions and explore the differences between tissue cryopreservation solutions and cell cryopreservation solutions.
Organ cryopreservation solution and cell cryopreservation solution Product Introduction
1. Organ cryopreservation solution: It is widely used for the transport of high-fidelity samples, such as primary tissues, transplanted organs, and single-cell sequencing specimens. Traditional sample‑preservation and transport methods—such as ultra‑low‑temperature storage and chemical fixation—often lead to adverse outcomes, including nucleic acid degradation in tissue cells, reduced transcriptome integrity, cell lysis, and contamination by free RNA. Our product fully immerses the sample and penetrates deep into the tissue, enabling transport at 4°C while preserving the informational integrity of precious specimens and minimizing batch‑to‑batch variability caused by transit. At the same time, it provides an optimal microenvironment for cells and tissues, preventing apoptosis and tissue necrosis that can result from improper storage. Moreover, samples can be stored at 4°C for up to 72 hours, maintaining cell viability above 90% and ensuring that tissues retain their full functional integrity.
2. Cell cryopreservation solution: It is compatible with the vast majority of tumor cells and conventional cell lines, as well as most stem cells, and cryopreserved cells can be stored long-term at −80°C. Free of animal‑derived proteins and serum components, it effectively minimizes contamination by bacteria, viruses, mycoplasma, and other microorganisms, ensuring the safety of cryopreserved cells. This cryopreservation solution contains DMSO, glucose, and various other cell‑culture nutrients, enhancing cell survival and viability, and is also suitable for serum‑free culture systems and protein‑expressing cell lines.
Organ cryopreservation solution and cell cryopreservation solution products Save effect
Cell cryopreservation solution: It emphasizes high cell recovery and viability, ensuring that cellular functions remain unaffected.
Tissue cryopreservation reagents: designed to preserve the structural integrity and functional activity of tissues over the long term, with post-thaw recovery… Cell viability remains above 90%. 。
Organ cryopreservation solution and cell cryopreservation solution Storage conditions when not in use
Cell cryopreservation solution: Store at room temperature. Keep refrigerated at 4°C; shelf life: 24 months.
Organ cryopreservation solution: Blue ice transport. Store at -20°C away from light; shelf life: 12 months. It can be stored at 4°C for two weeks; during this period, its color will change from colorless to light brown, without affecting product performance.
Organ cryopreservation solution and cell cryopreservation solution products Precautions for Use
▶ Organ cryopreservation solution:
1. Before use, thaw the product at 4°C. After thawing, a small amount of flocculent precipitate may appear; shake well until completely dissolved before use.
2. It is recommended to aliquot the product according to the actual amount used to avoid repeated freeze-thaw cycles.
3. Store in a sealed container; use with caution if the inner packaging is damaged.
▶ Cell cryopreservation solution:
1. After cells are aliquoted with cryopreservation solution, minimize the time they spend at room temperature and transfer them promptly to a −80°C ultra-low freezer.
2. For cryopreservation of stem cells (such as ES cells), it is recommended to conduct a trial culture and cryopreservation for more than one week prior to formal use, and to confirm cell viability before proceeding with long-term cryopreservation.
3. The product contains 10% DMSO. For cells that are sensitive to DMSO, we recommend performing a preliminary cryopreservation trial with this product for at least one week to verify its performance before proceeding with formal cryopreservation.
4. During cell recovery, the cryopreserved cells should be immediately placed in a 37°C water bath and gently shaken; rapid thawing helps improve recovery efficiency.
5. For relatively fragile or valuable cell lines, it is recommended that, after overnight storage at −80°C, they be transferred to a liquid nitrogen tank for long-term preservation.
In summary, both cell cryopreservation solutions and tissue cryopreservation solutions are essential biological materials that play an irreplaceable role in scientific research and medicine.
