Why do cell culture flasks need TC- treated?

Cell culture can be divided into adherent cells and suspension cells according to the different culture methods. Adherent cell culture needs to use TC-treated cell culture flasks, so why do TC-treated?

What is TC-treated?

The full name of TC-treated is Tissue culturetreated. TC-treated means that the cell culture flask has undergone surface modification treatment and is suitable for the culture of adherent cells.

Why do cell culture flasks need TC-treated?

Adherent cells need to have a support surface that can be attached, and rely on the attachment factors secreted by themselves or in the culture medium to grow and reproduce on the surface. Most animal cells are adherent cells. At first, the cell culture flasks on the market were mainly made of glass. The glass itself is hydrophilic, and the surface can be suitable for the growth of adherent cells without any treatment. However, in practical applications, the disadvantages of high cleaning cost and fragility of glass are gradually highlighted, and are gradually replaced by polymer materials with better performance.

For example, polystyrene (PS) has very good light transmittance and plasticity, and is non-toxic and odorless, making it the best choice for disposable cell culture consumables. However, the surface of this material is hydrophobic, so it needs to undergo surface modification treatment to enhance the ability of cell adsorption and protein binding, making it suitable for adherent cells to grow.

Therefore, in order to enhance the ability of cell adsorption and protein binding, and make it suitable for the growth of adherent cells, cell culture flasks generally need TC- treated.

The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.

In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.

Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.

In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
