J774A.1 Cells
General information
| Description | The J774A.1 cell line was derived from the ascites tumour of a female BALB/c/NIH mouse during plasmacytoma-inducing treatment. The cells are known for their ability to perform antibody-dependent phagocytosis, making them a helpful tool for investigating immune responses to various antigens. The growth of J774A.1 cells is inhibited by various substances, including dextran sulfate, p-phenylenediamine (PPD), and lipopolysaccharide (LPS). J774A.1 cells synthesize large amounts of lysozyme and are known to synthesize interleukin-1 beta continuously. The J774A.1 cell line has been used in various immunology and infectious disease studies. For example, it has been used to investigate the cytotoxicity of triazolo[1,5-a]pyridinium salts with leishmanicidal activity and the antitrypanosomatic activity of flavonoid glycosides isolated from Delphinium species. Overall, J774A.1 cells are a valuable tool in studying macrophage function, cytokine synthesis, and the immune response to various antigens and pathogens. |

|
| Shipping Conditions | Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage. |
| Storage Conditions | For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen. |
Quality control / Genetic profile / HLA
| Sterility | Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |

DMEM, w: 4.5 g/L Glucose, w: 4 mM L-Glutamine, w: 3.7 g/L NaHCO3, w: 1.0 mM Sodium pyruvateDMEM (Dulbecco's Modified Eagle Medium) is a highly versatile and widely utilized basal medium designed to support the growth of a diverse range of mammalian cells in biological research. It serves as an ideal medium for culturing primary fibroblasts, neurons, glial cells, HUVECs, smooth muscle cells, as well as popular cell lines like HeLa, 293, Cos-7, and PC-12.
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.€75.00*PBSPhosphate-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.
