  Once the cells we culture in   cell factory   are contaminated, most of them are difficult to handle. If the contaminated cells are valuable and difficult to obtain again, the following methods can be used to remove them. 1. Use antibiotics Antibiotics are more effective at killing bacteria in cell factories. Combination medication is more effective than medication alone. Preventive medication is more effective than medication after contamination. Preventive medication generally uses a double antibiotic (penicillin 100u/mL plus streptomycin 100μg/mL). After contamination, the cleaning method needs to be 5 to 10 times greater than the usual amount. The drug should be used for 24 to 48 hours after the addition, and then replaced with the usual routine. Culture fluid. This method may be effective in the early stages of contamination. In addition to penicillin and streptomycin, the antibiotics used can also include gentamicin, kanamycin, polymyxin, tetracycline, nystatin, e...

  When we use   cell factories   to culture cells, the growth status of the cells is affected by various factors. These factors may seem inconspicuous, but if not paid attention to, they will cause heavy damage to the cells. So, how do small details when using cell factories affect cell growth, and how can we avoid pitfalls when using cell factories to culture cells? 1. Degree of contact between cells Normal cells (diploids) have attachment contact inhibition, and cell growth stops after overgrowth. However, abnormal cells such as tumor cells have weak contact inhibition and can grow to higher cell densities, but some cells overgrow. The damage is difficult to reverse, so it is not recommended to have too high a cell density when culturing cells. Important points: Generally, cells cultured in a cell factory can be passaged when the cell confluence reaches 70-80%. Do not overgrow the cells. Cell Factory Systems 2. Cell growth attachments Adherent cells will adhere to the w...

  When we use cell culture consumables such as   cell factories   to culture cells, we need to perform routine inspections on the cells. Observe the cell morphology and growth, as well as the pH changes of the culture, the presence of pollution, etc. According to the dynamic changes of the cells, change the medium or pass the cells. If any abnormalities are found, timely measures should be taken. Generally, observations will be made from the following four aspects: 1.Cell morphology Cells in good growth status can be seen under a general microscope. The cells are highly transparent, refractive, and have unclear outlines. When cells grow poorly, their outlines are enhanced, vacuoles, lipid droplets, and other granular objects often appear in the cytoplasm. The gaps between cells increase, and the cell shape can become irregular or even lose its original characteristics. Such as epithelial cells becoming epithelial-like cells, etc. 2. Cell growth After the primary culture o...

  Cell factories   are specialized culture vessels used for large-scale production of cells, such as mammalian or microbial cells, for various applications including biopharmaceutical production, vaccine development, and tissue engineering. While cell factories typically do not use caps in the traditional sense, as they are often equipped with specialized closures or systems to ensure a sterile and controlled environment, there are several components that play a crucial role in their operation. Here are some of the important components used in cell factories: 1.Sterile Filters: Cell factories require aeration and gas exchange while maintaining sterility. Sterile filters are essential components that are integrated into the design of cell factories. They allow the exchange of gases, such as oxygen and carbon dioxide, while preventing the entry of contaminants. These filters are typically made of materials that provide both filtration and microbial retention capabilities. 2.Tubi...

Operating a cell factory involves the controlled cultivation and manipulation of cells to produce specific products or compounds. Cell factories are commonly used in biotechnology, pharmaceuticals, and industrial processes. Here's a general overview of how to operate a   cell factory : 1.Select the Host Organism: Choose a suitable host organism for your specific application. Common choices include bacteria (e.g., Escherichia coli), yeast (e.g., Saccharomyces cerevisiae), mammalian cells (e.g., Chinese hamster ovary cells), and plant cells. The choice of host organism depends on factors such as the product to be produced, scalability, and the ability to genetically engineer the organism. 2.Genetic Engineering: If necessary, genetically modify the host organism to make it capable of producing the desired product or compound. Introduce or modify genes within the host's genome to enable the production of the target molecule. 3.Cultivation: Grow the genetically modified cells in a c...

  The purpose of surface TC treatment in   cell factory systems   is to improve conditions for cell attachment and growth and to increase the efficiency of cell processes. Here are some of the main reasons for surface TC treatment: 1. Improve cell attachment: Surface TC treatment can form a layer of coating or matrix on the surface of the matrix of the cell factory, providing a suitable environment for cell attachment. This coating is usually a highly biocompatible material, such as collagen, gelatin or polylactic acid, which can be used for surface treatment of cell culture media. Through surface TC treatment, cell adhesion factors, growth factors and extracellular matrix components required for cell adhesion can be provided, thereby enhancing the interaction between cells and the matrix, and facilitating the attachment and growth of cells in the factory. 2. Promote cell proliferation: Surface TC treatment can provide suitable surface properties required for cell divisio...

  Cell culture consumables are necessary items for culturing cells, and play an important role in creating a good growth environment for cells and ensuring their normal reproduction. Cells are sensitive to the environment, especially the requirements for consumables are relatively high, and one of the most important points is the surface TC treatment. Cell Factory Systems TC treatment is a treatment method, and the cell culture consumables treated with TC can promote cell adherent growth and morphological extension. At present, adherent cell culture is still the mainstream culture method in the market, and most animal cells need to be attached to a solid phase interface to grow. Cells can only attach to a hydrophilic solid phase interface. The earliest cell culture vessels were made of glass. Because the surface of the glass is hydrophilic, the surface can be suitable for cell growth without special treatment. However, most of the cell culture consumables on the market are mainly p...

  Adherent cells are relatively common cell types.

  Most of the cells cultured in vitro belong to adherent cells. The growth of this type of cells must have a support surface that can be attached. Cells can grow and reproduce on the surface by relying on the attachment factors secreted by themselves or provided in the medium. So, what are the requirements for cell culture consumables for adherent cells? Cell Factory Systems The anchorage-dependent cells should be attached to the wall of the culture (flask) vessel during culture. Once the cells are attached to the wall, they will spread rapidly, then start mitosis, and soon enter the logarithmic growth phase. Generally, after a few days, the culture surface will be covered and a dense monolayer of cells will be formed. Cell culture consumables for adherent cells include  cell factory systems , cell culture plates, cell culture roller bottles, etc. At present, most of the cell consumables on the market are polymer materials such as PS, PC, which do not have glass materials. Due...

  As a multi-layer cell culture container,   cell factory systems   are widely used in vaccine preparation, biomedicine, cell therapy and other fields. The correct operation method is the key to ensure the effect of cell culture, so we need to pay attention to the following points when culturing cells: 1. Preheating in advance: The cell factory systems are a commonly used tool for large-scale cell culture. Due to the relatively large culture area, it takes a long time to reach the set culture temperature. We can preheat the container and the required medium before the start of the experiment, which can effectively accelerate the speed of cell attachment and help improve the cell recovery rate. 2. Horizontal placement: Whether the cells are evenly distributed is also one of the factors that affect cell growth, so we must pay attention to horizontal placement when placing the culture container to avoid uneven cell distribution due to uneven surface. Cell Factory Systems 3. ...
