Ham's F-12 Medium, also known as Ham's F-12 Nutrient Mix, is a widely used basal medium designed specifically for cell culture. It has been extensively employed for serum-free, single-cell plating of Chinese Hamster Ovary (CHO) cells, lung cells, and mouse L cells. Additionally, Ham’s F-12 is the medium of choice for a Clonal Toxicity Assay (CTA).
One of its notable advantages is the ability to support cell growth without the need for serum supplementation. This eliminates potential interference caused by serum components, ensuring consistent and reliable experimental results. By providing a serum-free culture environment, Ham's F-12 Medium offers researchers greater control over their investigations.
Another key feature of Ham's F-12 Medium is its suitability for single-cell plating. This makes it an excellent choice for a variety of cell lines, including CHO cells, lung cells, and mouse L cells. The medium's optimized nutrient composition facilitates efficient attachment and growth of individual cells, enabling the establishment of homogeneous cell cultures with improved reproducibility.
Moreover, Ham's F-12 Medium has gained recognition as the preferred medium for the Clonal Toxicity Assay (CTA). This assay plays a critical role in assessing the cytotoxic effects of substances on cells. By utilizing Ham's F-12 Medium in the CTA, researchers can accurately evaluate the impact of various compounds or treatments on individual cells, providing valuable insights into toxicological profiles.

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
Phosphate-buffered saline (PBS) is a widely used buffer solution in biological and chemical research. It plays a crucial role in maintaining the pH balance and osmolarity during various experimental procedures, including tissue processing and cell culture. Our PBS solution is meticulously formulated with high-purity ingredients to ensure stability and reliability in every experiment. The osmolarity and ion concentrations of our PBS closely mimic 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:

8000 mg/L Sodium chloride (NaCl)
200 mg/L Potassium chloride (KCl)
1150 mg/L Sodium phosphate dibasic anhydrous (Na2HPO4)
200 mg/L Potassium phosphate monobasic anhydrous (KH2PO4)

This composition ensures an optimal pH and ionic balance, suitable for a wide range of biological applications.

Applications of Our PBS Solution
Our PBS solution is ideal for various applications in biological research. Its isotonic and non-toxic properties make it suitable for substance dilution and cell container rinsing. PBS solutions containing EDTA are effective for disengaging attached and clumped cells. However, divalent metals such as zinc should not be added to PBS, as this can cause precipitation. In such cases, Good's buffers are recommended. Additionally, our PBS solution is an acceptable alternative to viral transport medium for the transport and storage of RNA viruses, including SARS-CoV-2.
