What Are Cell Culture Flasks Treated With?

Cell culture flasks are typically used to grow a wide variety of organisms, including fungi, bacteria, and viruses. These microorganisms can be harmful to humans, so these flasks are often treated to minimize their growth. Saining Cell Culture Flask is one type of surface treatment that is applied to large 175 cm2 flasks. In addition, it is also available in larger sizes like 225 cm2 flasks.

Polystyrene
To maintain the integrity of a cell culture experiment, it is essential to choose the right vessel. For results, a flask must be free of contaminants. This means that it cannot harbor any materials that could harm a cell culture experiment, such as BSE and TSEs. Polystyrene is a popular choice for cell culture vessels because it offers both formability and functionality.
Historically, polystyrene has been the fundamental substrate for adherent cell culture. But polystyrene has other benefits besides its hydrophobic properties. For example, it can be treated to make it hydrophilic and negatively charged. This property is beneficial for a wide range of laboratory applications, including tissue culture and molecular biology. Moreover, it is non-toxic, making it ideal for cultured cells.
The surface of polystyrene can be treated to improve cell attachment and migration. The surface is treated by coating it with polysaccharides or proteins. This coating is especially useful when a serum-free condition is used. Since serum normally contains attachment proteins such as fibronectin, many cell types struggle to attach to polystyrene surfaces. With these modifications, the polystyrene surfaces are much better suited for cell culture.
Vacuum gas plasma
Cells have a hard time adhering to polystyrene, a common material used in labware. To overcome this problem, the surface of the polystyrene flask must be modified to be hydrophilic. Vacuum gas plasma (VGP) treatment, a proprietary process, can achieve a uniform surface chemistry that improves the attachment of cells.
Cell Culture Flasks features a vacuum gas plasma treatment, which helps increase the cell attachment and growth. These flasks have a convenient pull strip for easy opening. The resealable ab provides protection against contamination. Vacuum gas plasma treatment is also a good choice for sterilization. It is safe for the cells in the flask, and it minimizes contamination risks.
VGP is a powerful technology that adds chemical barrier layers to the surface of laboratory equipment. The process is a great alternative to liquid coatings, as the VGP ions do not dissolve plastic and are therefore non-reactive. Additionally, plasma treatment offers chemical functionality flexibility. If you are preparing cell culture flasks for the lab, consider using this technology. It will enhance your experiments and improve your quality of results.
Polystyrene cell culture flasks are treated with vacuum gas plasma to make them suitable for cell growth. In addition, they are made with special caps to prevent leaking and starvation. They are also designed with a large mouth, so you can insert a cell scraper easily. This treatment will ensure the quality results and minimize the risk of contamination.
Poly-lysine
A positive-charged amino acid chain, poly-L-lysine is used as a coating on cell culture flasks and plates. It has been found to enhance cell adhesion and increase the number of positively charged cell binding sites. This treatment also enhances the growth and survival of primary neurons in culture. However, before it can be used for cell culture, it is important to know the correct conditions for each cell line and application.
Poly-D-lysine coating is inefficient when prepared with distilled water. The solution should have a pH ranging from 3.3-6.6. A solution containing a borate buffer of 8.5 is recommended for improving coating efficiency. Once the poly-D-lysine is coated, it must be rinsed thoroughly in fresh media to remove any remaining coating.
One way to coat plastic and glassware with poly-D-lysine is by using a solution with a molecular weight of 70-150kd. This solution is diluted to 50ug per ml and applied to the surface of the culture flask. Then, the culture flask is incubated at room temperature for 5 minutes.
