The application of horse serum and the characteristics of PETG media bottle

图片
  Serum is a nutrient required for cell culture. There are many types of serum. In addition to the bovine serum we often say, horse serum is also commonly used. So which cells are this serum mainly used for, and what are the characteristics of the   PETG media bottle   as its container? Serum refers to the light yellow transparent liquid separated from the fibrin in the plasma after blood coagulation, or refers to the plasma from which the fibrin has been removed. The main function is to provide basic nutrients, hormones and various growth factors, binding proteins, contact-promoting and stretching factors to protect cells from mechanical damage and protect cells in culture. Horse serum is collected from healthy horse blood as raw material, aseptic blood collection in a closed system, and microporous filtration. It is a clear liquid, free of bacteriophage, ultra-low endotoxin, no hemolysis, no foreign matter, no bacteria, fungi, mycoplasma, mycoplasma, chlamydia, etc., promoting The ef

Why PETG media bottles are square

  Serum is an essential nutrient for cell growth, and its quality is related to the growth status of cells. To ensure the quality of serum, a high-quality   PETG media bottle   is essential. The shape of this bottle is generally square, why is that? 1. Easy to take: Cell culture is a very cumbersome task. It is necessary to observe the growth status of the cells at any time, and decide whether to add serum according to the specific situation. After the cells grow to a certain extent, the nutrients in the serum are exhausted, and the serum inside the cell culture consumables needs to be replaced to provide a continuous supply of nutrients for the cells. Therefore, in the process of cell culture, the operation of taking serum is very frequent. The PETG media bottle with a square design is more convenient to grasp and convenient for experimenters to operate. 60ml PETG Media Bottles 2. High utilization rate: The square design has a larger storage capacity than the round shape, which can in

How to Aliquot Fetal Bovine Serum into PETG Media Bottles

图片
Serum is a nutrient required for cell growth, among which fetal bovine serum is of better quality. This is because fetal cows have not been in contact with the outside world, and the serum contains few antibodies and complements that are harmful to cells. When using serum, we often have to divide the serum into   PETG media bottles . How to divide it? Fetal bovine serum is a slightly viscous liquid with light yellow and clear appearance, no hemolysis, and no foreign matter. Because of its special use, it is easy to introduce various sources of pollution if you do not pay attention during the packaging process. Contaminated serum is used for cell culture It will affect the normal growth of cells. Therefore, when subpackaging fetal bovine serum, you must follow the prescribed steps: PETG Media Bottles Inactivation: water bath, 56°C, 30 minutes, and shake evenly at any time. Take it out, put it on ice immediately, and let it cool down to room temperature naturally (about 1-3 hours). Durin

  Fudau Biotech will participate in the PITTCON 2023  Time: March 20-22 Location: Philadelphia - Pennsylvania Convention Center Fudau Booth No.: 841 Wonderful exhibits first look: Part1 | Biotechnology Fudau biotechnology consumables are mainly used in large-scale cell culture, such as biopharmaceuticals, vaccine preparation and other fields. High-efficiency shake flasks and cell factories are equipped with special pipeline systems, which can realize the closed aseptic transfer of liquids and reduce the risk of external source contamination. The expanded surface roller bottle has a larger culture area, and the TC-treated surface ensures the consistency of cell culture. The 10L PC carboy can withstand high temperature treatment and low temperature cryopreservation, and is an ideal choice for storing sterile liquids, dispensing solutions and culture media. Cell Factory Part2 | Laboratory Cell Culture Fudau laboratory cell culture consumables include cell culture flasks, multi-well cell c

Application of PETG material in media bottle

  PETG is a kind of transparent plastic, which belongs to non-crystalline copolyester. It has good viscosity, transparency, color, chemical resistance, and stress whitening resistance. It can be thermoformed or extrusion blow molded very quickly. It is a good choice for making media bottle of good raw material. PETG raw materials have the following characteristics: 1. Thermoforming performance PETG is easy to produce products with complex shapes and large draw ratios. This material does not need to be pre-dried before thermoforming. The molding cycle is short, the temperature is low, and the yield is higher. 2. Toughness Extruded sheets of PETG are generally 15 to 20 times tougher than general-purpose acrylics and 5 to 10 times tougher than impact-modified acrylics, and have sufficient bearing capacity during processing, transportation and use to help prevent rupture. PETG Media Bottles 3. Weather resistance PETG offers excellent weather resistance. It maintains the firmness of the pro

Reasons for Cell Factory Surface Treatment

  The   cell factory   plays an important role in the large-scale cultivation of cells, and has low risk of contamination. It can utilize the maximum cultivation area in a limited space, save a lot of factory space, and reduce the cost of quality control and downstream purification of the enterprise. cost advantages. This kind of culture consumables generally needs surface treatment before it can be used for cell culture. Why? According to different growth modes, cells are divided into adherent cells and suspension cells. The growth of such cells must have a support surface that can be attached, and the cells rely on the attachment factors secreted by themselves or provided in the medium to be on the surface. Growth, propagation, and suspension cells are not required. The cell factory is made of polystyrene raw material, which itself is hydrophobic, which is not conducive to the growth of cell attachment. Therefore, it needs to be modified on the surface to become hydrophilic before it

How Cell Factories Help Efficient and Stable Production of Vaccines

图片
  Cell factory   is a common cell consumable for large-scale cell culture. It is mainly used in the vaccine industry, cell gene therapy and stem cell fields. So how does the cell factory help the efficient and stable production of vaccines? The industrial production of vaccines is extremely challenging. In the process, cell expansion is involved. Given the complexity of the production process, how to safely and stably scale up has become the focus of the industry. The principle of cell culture expansion is that large-scale culture and small-scale culture maintain a relatively stable environment, and only in the same environment can cell growth density, viability and product expression remain stable. A cell factory is a delicately designed cell culture device, which takes up less space, reduces pollution, increases yield, and has good controllability. It is accepted by more and more biopharmaceutical manufacturers and scientific research institutions. The cell factory realizes the expan

What are the common specifications of serum bottles

  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
