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.

EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 1.5 g/L NaHCO3, w: EBSS, w: 1 mM Sodium pyruvate, w: NEAA
€25.00*
One of the most widely used synthetic cell culture media is Minimum Essential Medium Eagle (MEM). Developed by Harry Eagle, this medium was first introduced in 1959 and has since become a popular choice for various cell types grown in monolayers and adherent cell lines.
This EMEM medium consists of 2 mM L-Glutamine, 1.5 g/L NaHCO3, EBSS, 1 mM Sodium pyruvate, and NEAA.
What's in EMEM?
EMEM is a modified version of Eagle's minimum essential medium, containing Earle's Balanced Salt Solution, non-essential amino acids, L-glutamine, sodium pyruvate, and sodium bicarbonate. It's important to note that this reduced level of sodium bicarbonate (NaHCO3, 1.5 g/L) is intended for use in 5% CO2 in the air. To maintain its effectiveness, storing the medium at two °C to 8°C in the dark when not in use is recommended.
What is EMEM used for?
Eagle's minimal essential medium (EMEM) is a cell culture medium that can maintain cells in tissue culture. The medium contains higher concentrations of amino acids, allowing for a more accurate approximation of the protein composition of cultured mammalian cells. EMEM may be used to cultivate various cells, including fibroblasts, human liver cancer cell line (HepG2) cells and human fetal brain progenitor-derived astrocyte cells (PDA). It is typically used in the presence of fetal bovine serum (FBS), calf, or horse sera.
How is EMEM different from other cell culture media?
While EMEM and Dulbecco's modified Eagle's medium (DMEM) share some similarities, they also differ. Both media lack protein and contain the amino acids, salts, glucose, and vitamins required to provide a cell with energy and maintain it in tissue culture. However, the DMEM formulation is modified to contain up to four times more vitamins and amino acids and two to four times more glucose than EMEM. It's worth noting that EMEM is also different from the original MEM formulation.
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.
