Why do cell culture dishes need surface treatment?

In order to meet the requirements of cell culture experiments and to achieve the desired results, we usually use TC treatment, TC-enhanced treatment and ultra-low attachment treatment for suspended cells.

1. TC treatment , suitable for the culture of adherent cells

With special vacuum gas plasma treatment, the surface layer can be consistently and uniformly charged with both positive and negative groups for a long period of time, which ensures a more uniform and stable cell attachment. The introduction of double charge makes the TC surface for endothelial, hepatocyte and neuron cell culture have better adhesion and spreading than similar TC surfaces, and it can achieve the optimal performance of cell adhesion to meet the culture of a higher level of adherent cells. The surface can achieve the best cell adhesion performance and meet the higher level of adherent cell culture.

2. TC-enhanced treatment，suitable for Cell Cultures with High Adhesion Requirements

Advanced tissue culture treatment, compared with standard TC-treated products, TC-enhanced surface has the ability to promote cell adhesion and extension, rapid expansion of cell populations, can be used for the propagation of demanding cells, such as primary or sensitive cells, as well as cells cultured under restrictive growth conditions (serum-free or reduced serum), increased rapid expansion of cell populations, promotion of cell adhesion and extension, can be stored at room temperature for a wider range of applications.

3. Ultra-low adsorption series for suspension cell culture

Special amphoteric molecular polymer is coated onto the surface of the culture vessel. Since this compound is particularly hydrophilic, the amphoteric molecules can adsorb water molecules to form a wall of water, so that cells, protein molecules, bacteria and other substances can not be adhered to the culture vessel, resulting in ultra-low cell adherence, which can be cultured in suspension for more than 15 days.

It can be used for the culture of fetal cells, hemocytes and other cells that need to grow in suspension culture medium, as well as to promote the culture of 3D spheroid cells and organoids, and it has anti-adhesion properties to strong adhesive cells.
