SW620 Cells








Basic details about the SW-620 cancer cell line
Description | The SW-620 cell line, originating from the large intestine of a 51-year-old male with Dukes-C colorectal cancer, is a pivotal research model in colorectal cancer, especially for cancer biomarkers, chemotherapy, and the study of metastatic cancer cells. SW-620 cells are pivotal for studying cell apoptosis and the resistance mechanisms to anoikis, a form of programmed cell death crucial for preventing metastasis. Research utilizing the SW-620 colon cancer cells has delved into proteomic analysis to understand proteome changes under different conditions, such as hypoxia. Hypoxic SW620 cells exhibit specific proteome adaptations that contribute to chemotherapy resistance. SW620 colon cancer cells have been pivotal in evaluating natural compounds like curcumin and their impact on cancer cell viability. Studies have shown that curcumin inhibits cell viability in SW-620 cells. Moreover, the cell line aids in assessing the effects of chemotherapeutic agents and the potential for chemotherapy resistance, which is critical for advancing cancer treatment strategies. Exhibiting high tumorigenic and metastatic capabilities, SW-620 cells form solid tumors in vivo. The SW620 xenograft model, alongside the study of specific pathways like the catenin pathway and the role of transcription factors such as cdx2 in colonic adenocarcinoma cells, enriches our understanding of colorectal cancer's molecular underpinnings. In summary, SW-620 human colon adenocarcinoma cells are an invaluable resource in cancer research, offering a multifaceted approach to understanding colorectal cancer's complexities. |

Subculturing | Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium. |

What sets DMEM apart from other media is its unique composition. It contains an impressive fourfold increase in amino acid and vitamin concentration compared to the original Eagle's Minimal Essential Medium. Initially developed with low glucose (1 g/L) and sodium pyruvate, DMEM is frequently employed with higher glucose levels, either with or without sodium pyruvate. Notably, DMEM does not contain proteins, lipids, or growth factors, necessitating supplementation. To achieve optimal growth, a common approach is to supplement DMEM with 10% Fetal Bovine Serum (FBS). Additionally, DMEM employs a sodium bicarbonate buffer system, requiring a 5-10% CO2 environment to maintain a physiological pH.
Dulbecco's Modified Eagle Medium (DMEM) is highly regarded among defined media for cell and tissue culture, catering to the growth needs of various adherent cell phenotypes. It surpasses the original Eagle's Medium, developed in the 1950s for cultivating chicken cells, through the enhanced supplementary formulation known as Dulbecco's modification. This modification significantly elevates the content of select amino acids and vitamins up to fourfold compared to the original medium.
In the field of cell culture, DMEM plays a vital role as a growth medium for different cell types, including primary cells, stem cells, and transformed cells. Researchers also employ the modified version of DMEM for a wide array of research applications, such as drug discovery, tissue engineering, and the study of cell signaling pathways.

- 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.
