What to do about vacuolization of cells in cell culture flasks

 Cells are very sensitive substances, and a sterile environment, suitable temperature, osmotic pressure, carbon dioxide, etc. are all necessary environments for their growth. In the process of culturing cells, vacuolation is a common problem. What is cell vacuolization? What should I do if the cells in the cell culture flasks are vacuolated?

Cell vacuolation refers to the appearance of vacuoles (vesicles) of different sizes in the cytoplasm and nucleus of degenerated cells, and the cells are cellular or reticular. In severe degeneration, small vesicles fuse with each other into large vesicles, the nucleus is suspended in the center, or squeezed to one side, the cell body is significantly enlarged, the cytoplasm is blank, and the shape is like a balloon.

This phenomenon is common, and some cells themselves have certain vacuoles (such as HepG2, Ishikawa and some drug-resistant strains, etc.). If only a few cells have very few vacuoles, it is likely that the cell state is not good. The cell state can be adjusted by adjusting the serum concentration, controlling the digestion, and controlling the passage ratio and time. Some cells have vacuoles, and the number of vacuoles in a single cell is too large, which may be caused by high cell generation and cell aging, and cells with earlier generations need to be replaced.

To sum up, if it is found that the cells in the cell culture flask are vacuolated, do not be too nervous, analyze the actual situation of the vacuolation phenomenon, and make corresponding adjustments.

Material features of PETG media bottles

图片
  PETG media bottles   are a special packaging for storing various media, reagents, serum and other solutions, and it is also a product that scientific researchers have more contact with. The wide range of applications is mainly due to the superior properties of its materials. PETG is a transparent plastic that belongs to the non-crystalline copolyester. Serum needs to be stored in a low temperature environment. The use range of this material is -80°C to 60°C, which makes PETG media bottles fully meet the storage needs of serum. In addition, it has the following features: 1. High transparency, the light transmittance reaches 90%, which can reach the transparency of plexiglass; 2. It has stronger rigidity and hardness, excellent scratch resistance, impact resistance and toughness, which is close to or even exceeds that of polycarbonate (PC), and is suitable for injection molding, extrusion molding and extrusion blowing processing; 3. In terms of chemical resistance, oil resistance, weat

What are the common specifications of serum bottles

图片
  In biological laboratories, we often have to store various solutions and reagents. Thanks to the advantages of good performance, transparency, and temperature resistance, serum bottles have become "frequent visitors" in the laboratory. As a commonly used storage container, what are its common specifications?                      FuDau 60ml-Square-PETG-PET-Media-Bottles Common materials for serum bottles include PETG and PET, both of which have very good temperature resistance and transparency. In comparison, bottles made of PETG have more advantages in terms of barrier properties. If you want to pursue a better storage state of the solution, it is recommended to use a bottle made of PETG. There is a molded scale on the body of the bottle, we can clearly observe the capacity and state of the solution. The common specifications of this kind of container include 5ml/10ml/30ml/60ml/125ml/250ml/500ml/1000ml, etc., which are mostly used to store serum, culture medium, buffer, dis

Cell factory requirements for production raw materials

图片
Cell factories   are mainly used for large-scale cell culture. Cells have high requirements on the environment, such as temperature, humidity, osmotic pressure, pH value, etc. Therefore, this kind of   cell   consumables also has high requirements on raw materials. The first is transparency. In the process of cell culture, it is necessary to grasp the growth state of the cells at any time, and make corresponding adjustments according to the cell proliferation. Therefore, the raw materials of the cell factory must meet the requirements of transparency, so that it is convenient for researchers to observe the growth of cells. The second is the compatibility of materials. The raw materials of this consumable generally meet the requirements of USP Class VI medical polymer materials. Medical polymer materials refer to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices, and their sources include natural biopolymer mate
