Using CM-1 for Freezing Cells
To use CM-1 for freezing both adherent and suspension cells, follow these steps:
For adherent cells, wash and dissociate them from the culture substrate. For suspension cells, proceed directly to the next step.
Count the cells to ensure they are at the proper concentration.
Centrifuge the cells to pellet them, then resuspend in CM-1 freeze medium.
Transfer the resuspended cells into cryovials.
Use a slow-freezing method before transferring the cells to long-term storage.

RPMI 1640, w: 2.1 mM stable Glutamine, w: 2.0 g/L NaHCO3
€25.00*
RPMI 1640 Medium, also known as RPMI medium, is a highly versatile cell culture medium widely utilized in biological research to cultivate various mammalian cells. Developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at the renowned Roswell Park Comprehensive Cancer Center, this medium derived its name from its origin at the Roswell Park Memorial Institute (RPMI).
Initially designed to support the growth of human leukemic cells in both suspension and monolayer cultures, RPMI 1640 Medium has evolved through modifications by researchers and commercial suppliers to become suitable for a diverse range of mammalian cells. It is exceptionally compatible with cell lines such as HeLa, Jurkat, MCF-7, PC12, PBMC, astrocytes, and carcinomas.
RPMI 1640 Medium stands apart from other cell culture media due to its unique composition. It contains a substantial amount of phosphate, amino acids, and vitamins. Notably, it encompasses biotin, vitamin B12, and PABA, absent in Eagle's Minimal Essential Medium or Dulbecco's Modified Eagle Medium. Moreover, RPMI 1640 Medium exhibits significantly elevated concentrations of vitamins inositol and choline. However, it does not contain proteins, lipids, or growth factors. Consequently, supplementation with 10% Fetal Bovine Serum (FBS) is commonly required to provide optimal conditions for cell growth.
The buffering system of RPMI 1640 Medium relies on sodium bicarbonate (2.0 g/L) and necessitates a 5-10% CO2 environment to maintain a physiologically appropriate pH. The inclusion of the reducing agent glutathione further distinguishes this medium from others.
The unique composition of this RPMI formulation comprises 2.1 mM of stable Glutamine, 2.0 grams per liter of NaHCO3, and phenol red.
Quality control
pH = 7.2 +/
- 0.02 at 20-25°C.
Each lot has been tested for sterility and absence of mycoplasma and bacteria.
Maintenance
Keep refrigerated at +2°C to +8°C in the dark. Freezing and warming up to +37° C minimize the quality of the product.
Do not heat the medium to more than 37° C or use uncontrollable sources of heat (e.g., microwave appliances).
If only a part of the medium is to be used, remove this amount from the bottle and warm it up at room temperature.
Shelf life for any medium except for the basic medium is 8 weeks from the date of manufacture.

Phosphate-Buffered Saline (PBS) Solution: The Optimal Buffer for Your Biological Research
Phosphate-buffered saline (PBS) is a versatile buffer solution used in many biological and chemical applications, as well as tissue processing. Our PBS solution is formulated with high-quality ingredients to ensure a constant pH during experiments. The osmolarity and ion concentrations of our PBS solution are matched to those of the human body, making it isotonic and non-toxic to most cells.
Composition of our PBS Solution
Our PBS solution is a pH-adjusted blend of ultrapure-grade phosphate buffers and saline solutions. At a 1X working concentration, it contains 137 mM NaCl, 2.7 mM KCl, 8 mM Na2HPO4, and 2 mM KH2PO4. We have chosen this composition based on CSHL protocols and Molecular cloning by Sambrook, which are well-established standards in the research community.
Applications of our PBS Solution
Our PBS solution is ideal for a wide range of applications in biological research. Its isotonic and non-toxic properties make it perfect for substance dilution and cell container rinsing. Our PBS solution with EDTA can also be used to disengage attached and clumped cells. However, it is important to note that divalent metals such as zinc cannot be added to PBS as this may result in precipitation. In such cases, Good's buffers are recommended. Moreover, our PBS solution has been shown to be an acceptable alternative to viral transport medium for the transport and storage of RNA viruses, such as SARS-CoV-2.
Storage of our PBS Solution
Our PBS solution can be stored at room temperature, making it easy to use and access.
To sum up
In summary, our PBS solution is an essential component in many biological and chemical experiments. Its isotonic and non-toxic properties make it suitable for numerous applications, from cell culture to viral transport medium. By choosing our high-quality PBS solution, researchers can optimize their experiments and ensure accurate and reliable results.
