C6 Cells
















General information
Description | The C6 cell line maintains glial cell type with fibroblast morphology and originates from a glioma of a Wisthar-Furth rat. The glioma was induced by exposure to N-nitrosomethylurea, following numerous cycles of alternating culture and animal passages. The C6 glioma cell line is frequently utilized in neuro-oncology research to create animal models that closely mimic the characteristics of human glioma, aiding in the development of new therapeutic agents and strategies. It is particularly effective in 3D cell culture and high-throughput screening. C6 cells are genetically diverse, possessing a wild-type p53 gene, increased Rb gene expression, and a mutant p16/Cdkn2a/Ink4a locus but lacking p16 and p19ARF mRNA expression. They also overexpress several genes in human gliomas, such as PDGFβ, IGF-1, EGFR, and Erb3/Her3 precursor proteins. However, the expression of IGF-2, FGF-9, and FGF-10 is reduced, while MMP-7 gene expression remains unchanged. Like human gliomas, C6 cells show increased activity of the Ras pathway genes, which is regulated by the elevated expression of the Ras guanine triphosphate activator protein. The C6 cell line has been utilized in various studies. For instance, it was used to examine the ability of 2-(2,4-dihydroxy phenyl)thieno-1,3-thiazin-4-one (BChTT) to halt cancer cell proliferation and to investigate the mechanisms involved in this process. In another research, the cytotoxic and antioxidant properties of the supercritical CO2 extract (SCE) of an old man's beard (Usnea barbata) were studied using C6 cells. Interestingly, these cells have been reported to show increased levels of glyceryl phosphate dehydrogenase activity in response to glucocorticoids. |

Required products
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 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.

- A Gentle Alternative to Trypsin
Accutase is a cell detachment solution that is revolutionizing the cell culture industry. It is a mix of proteolytic and collagenolytic enzymes that mimics the action of trypsin and collagenase. Unlike trypsin, Accutase does not contain any mammalian or bacterial components and is much gentler on cells, making it an ideal solution for the routine detachment of cells from standard tissue culture plasticware and adhesion coated plasticware. In this blog post, we will explore the benefits and uses of Accutase and how it is changing the game in cell culture.
Advantages of Accutase
Accutase has several advantages over traditional trypsin solutions. Firstly, it can be used whenever gentle and efficient detachment of any adherent cell line is needed, making it a direct replacement for trypsin. Secondly, Accutase works extremely well on embryonic and neuronal stem cells, and it has been shown to maintain the viability of these cells after passaging. Thirdly, Accutase preserves most epitopes for subsequent flow cytometry analysis, making it ideal for cell surface marker analysis.
Additionally, Accutase does not need to be neutralized when passaging adherent cells. The addition of more media after the cells are split dilutes Accutase so it is no longer able to detach cells. This eliminates the need for an inactivation step and saves time for cell culture technicians. Finally, Accutase does not need to be aliquoted, and a bottle is stable in the refrigerator for 2 months.
Applications of Accutase
Accutase is a direct replacement for trypsin solution and can be used for the passaging of cell lines. Additionally, Accutase performs well when detaching cells for the analysis of many cell surface markers using flow cytometry and for cell sorting. Other downstream applications of Accutase treatment include analysis of cell surface markers, virus growth assay, cell proliferation, tumor cell migration assays, routine cell passage, production scale-up (bioreactor), and flow cytometry.
Composition of Accutase
Accutase contains no mammalian or bacterial components and is a natural enzyme mixture with proteolytic and collagenolytic enzyme activity. It is formulated at a much lower concentration than trypsin and collagenase, making it less toxic and gentler, but just as effective.
Efficiency of Accutase
Accutase has been shown to be efficient in detaching primary and stem cells and maintaining high cell viability compared to animal origin enzymes such as trypsin. 100% of cells are recovered after 10 minutes, and there is no harm in leaving cells in Accutase for up to 45 minutes, thanks to autodigestion of Accutase.
In summary
In conclusion, Accutase is a powerful solution that is changing the game in cell culture. With its gentle nature, efficiency, and versatility, Accutase is the ideal alternative to trypsin. If you are looking for a reliable and efficient solution for cell detachment, Accutase is the solution for you.
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.
